Magneto-optic Kerr microscope

for materials analysis

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 magneto-optical Kerr microscopic imaging system is based on the self-designed optical path structure, and the optoelectronic components of Olympus and Soleibo; it is used for magnetic domain imaging and dynamics research of magnetic materials/spintronic devices. Multifunctional Probe Station With in-plane magnetic field, vertical magnetic field, and multiple pairs of DC/HF probes - the perfect combination of magneto-optical imaging and spin transport testing! The maximum vertical magnetic field 1.8 T, 1.4 T in-plane magnetic field, 4K-873K variable temperature, can be used for imaging research of hard magnetic materials. Multifunctional control system Test signal control - Vertical magnetic field/in-plane magnetic field/current/microwave and other multiple signals, applied synchronously at μs level; The waveform, amplitude, frequency, relative delay and other parameters of each signal can be easily adjusted. Image processing - Real-time subtraction to eliminate background noise; - Automatic correction of vibration drift, etc. Signal analysis - Real-time display of current and magnetic field test signals; - Based on Kerr image analysis, perform hysteresis loop scanning on the sample locally (220 nm) or globally.
