HALL EFFECT MEASUREMENT SYSTEM is used to measure the important parameters of Semiconductor Materials such as Carrier Concentration, Mobility, Resistivity, and Hall Coefficient, and so on. These parameters must be grasped and controlled in advance in order to understand the electrical characteristics of semiconductor materials. Therefore, the Hall Effect Measurement System is an indispensable tool for understanding and studying the electrical characteristics of Semiconductor Devices and Semiconductor Materials. The experimental results are automatically calculated by the software, and the Bulk Carrier Concentration, Sheet Carrier Concentration, Mobility, Resistivity, Hall Coefficient, Magneto-Resistance, and other parameters can be obtained at the same time.Product Description
The static magnetic field active shielding system can offset the magnetic field fluctuations of the geomagnetic field in real time, thereby generating a 10nT zero magnetic environment in the geomagnetic environment. For example, the gradient magnetic field of 1nT or 0.1nT can be generated in the shielding room or shielding cylinder, the system can also generate any set magnetic field in three-dimensional components for scientific experiments and simulation of geomagnetic changes.Product Descriptions
The dynamic magnetic field shielding effect can reach a higher level (better than 5 nT). By using AC current to generate a magnetic field, it has higher DC and AC magnetic field shielding efficiency, more accurate trajectory tracking function, larger range, and higher response speed. The ability to generate magnetic fields with three components X, Y, and Z within the range of (0-100000 nT) magnetic fields can be precise up to 5 nT, making products and experiments in scientific research, military industry, and medical care extremely meaningful and widely used.The SB electromagnet is a double-yoke(H-Frame) , variable air gap magnetic field generation equipment with each pole being adjustable. From the excitation of the excitating power source, the field vector forms a closed loop, and a high uniform magnetic field can be generated between two poles, and the field direction is along the axial direction of pole caps. All SB electromagnets are equipped with a pair of standard replaceable pole caps made of purity iron, which can be replaced to suit to individual experiment requirements. The pure-iron structure is suitable for coils heat dissipation, and the option of cooling water system is also available for extend the operating time.
The Three-Axis Equal-Diameter Coil, which is a type of three-axis Helmholtz coil exclusively developed by our company, features the nominal diameter coil, the same number of winding turns, and the same specification of wires per axis.<br/> This winding construction allows the Three-Axis Equal-Diameter Coil to have the same resistance, inductance, homogeneity, and B/I coefficient per axis; The coil per axis is fixed to each other in the embedded form, of which this mechanical structure makes the coil to feature a small size and the greater accessibility to the working gap; the whole former is made of non-magnetic PMMA material, which is applied for the study of low and weak magnetic field, and which is very suitable for the shielding room and the magnetic shield. The highest magnetic field of a three-axis equal diameter coil can be designed to be from 0 to 5 Gs.

A vibrating sample magnetometer(VSM) is an instrument that is used to measure magnetic properties. It is also called a Foner magnetometer or M-H Curve Hysteresis Graph Test System. <br/> VSM is composed of a master device, an electromagnet, a vibrator, a
This power supply is a high stability bipolar constant current power supply (smooth zero crossing commutation without delay). The power supply adopts a linear power supply structure, with high output current stability, low ripple and noise. The output current of the power supply can be continuously changed between positive and negative rated maximum current, and the current is smooth and continuous zero, which can generate a smooth and stable magnetic field in the electromagnet or coil. With our high precision Gauss meter and probe (optional), the power supply can operate in magnetic field mode. The magnetic field value can be directly set in magnetic field mode,The power supply will adjust the output current to make the electromagnet quickly reach the set magnetic field, convenient and fast, and the magnetic field is stable.It can control the field independently or scan the magnetic field continuously. The current mode and magnetic field mode can be switched at any time according to the need, and the operation is flexible.
High Homogeneity coil, which is composed of multi-ring coils arranged along the axial direction, includes the common coils such as Barker Coil, Braunbek Coil, Maxwell Coil, Rubens Coil, and Magnetic-Moment-Free coil. Compared with the Helmholtz coil, the combined coil features the better magnetic field homogeneity under the same diameter, the higher homogeneity and larger homogeneity volume in the effective space, and is suitable for the high-precision and large-range magnetic field needs. This design can meet any parameter customization requirements.
HEA series power amplifiers are specially designed for the use of exciter, which can provide a stable and adjustable excitation current for the exciter.Under the action of the excitation current, the exciter generates an excitation force on the tested component that corresponds to the excitation current, and the magnitude and phase of this force are only related to the excitation current and the characteristics of the exciter itself, but which is independent of the tested component.<br/> HEA series linear power amplifiers has below advantages: stable performance, strong protection function, easy to operation, no impulse during startup, no pollution to the environment, safe and reliable use. In addition, HEA series linear power amplifiers have good adaptability, which is suitable for the impedance of its basic matching load. It is widely used in excitation of inductive loads such as electromagnets and Helmholtz coils.
A standard Magnet is a kind of permanent magnet which is specially designed for Hall Element Calibration,capable of generating a stable and uniform magnetic field between two magnetic pole.<br/> The Standard Magnets are manufactured with high-performance rare earth materials to ensure long-term maintenance of its excellent magnetic properties, and which is widely used in a variety of fields requiring accurate magnetic field calibration, such as laboratories, metrology institutes and industrial testing equipment
