250 Nm Kerr Microscope High Resolution Magneto Optical Kerr Effect Microscope

Multifunctional Spin-Test Magneto-Optic Kerr Microscope

Product Model:

KMPL-S

Equipment Description:

This instrument enables high-resolution magnetic domain imaging of magnetic materials and spintronic chips, with a resolution of up to 250 nm. It is equipped with a highly intelligent control system and multifunctional magnetic field probe station, integrating optical imaging, multi-dimensional magnetic fields, electrical transport characterization, microwave testing, and variable temperature modules. With a single button operation, it can observe magnetic dynamics under various excitation conditions, such as magnetic fields, currents, spin-orbit torque, and spin-transfer torque. It features microsecond-level fast-response magnetic fields for high-precision magnetic domain velocity and DMI measurements.
