Magneto-optic Kerr Effect System

The surface magneto--optic Kerr effect (SMOKE) system offered by Dexing Magnet is a high - sensitivity magnetometer. The hysteresis loop of the sample can be obtained by detecting the change of reflection intensity on the surface of the magnetic sample, and the Kerr angle and ellipsometry of the sample can be calculated by the hysteresis loop.

Magneto-optic Kerr Effect System

The advantages of the surface magneto-optic Kerr system over other magnetic measurement systems are as follows: the single point of micromagnetism of the sample can be tested and the anisotropy of the material can be easily tested. The surface magneto-optic Kerr effect (SMOKE) system is used to study magnetic thin films. Magnetic nanostructures and magnetic anisotropy are idea tools.

1. Recording magnetic head;
2. Magnetic film;
3. Special magnetic medium;
4. Magnetic field sensor.



1. Magnetic nanotechnology;
2. Spintronics/magnetoelectronic;
3. Magnetic random access memory.


Basic Functions

1. Kerr effect test of longitudinal, transverse and poloidal.
2. 360-degree electric rotation sample, the anisotropy of the sample can be tested.
3. The Kerr effect at different points on the surface of the sample can be measured by manual displacement of sample, both left and right and up and down.
