Kerr Effect Hysteresis Loop Measurement Instrument Scientific Research Measurement Instrument
Hysteresis Loop Measurement Instrument For Scientific Research
Using the magneto-optical Kerr effect, this instrument provides high-precision characterization of magnetism in ferromagnetic, artificial antiferromagnetic, 2D materials, and microelectronic devices. It can simultaneously scan in-plane and out of plane magnetic fields to obtain hysteresis loops for any combination of in-plane/out of plane magnetic fields and in-plane/out of plane components. With a Kerr angle detection precision of up to 0.3 mdeg (RMS), it can detect the magnetization strength of single-atom layers and provides a tiltable sample holder for electrical/magneto-optical property characterization.
