The magneto-optical Kerr microscopic imaging test system can clearly and intuitively understand the spatial distribution and time evolution of the magnetization state in magnetic materials and devices, and is suitable for testing and product development of magnetic materials and spintronic devices.
The DXMOKE series magneto-optical Kerr effect system can directly obtain the longitudinal, transverse and polar Kerr rotation angle or the hysteresis loop of ellipticity, and can also obtain magnetic properties such as coercive force and saturation magnetic field. The magneto-optical Kerr effect system(MOKE) is an ideal tool for studying magnetic thin films, magnetic nanostructures and spintronics.
Using the magneto-optical Kerr effect to measure the hysteresis loop has the advantages of fast speed, high precision, non-contact, and no damage (no additional processing of the sample is required), and can obtain the coercive force, saturation magnetic field and remanence of magnetic materials.
Using the poloidal magneto-optical Kerr effect (MOKE), the magnetic properties of wafer stacks are quickly and globally detected. Non-contact measurement avoids damage to the wafer by traditional magnetic characterization, and can be applied to sample detection before and after patterning.
