Magneto Optical Kerr Effect Measurement System (MK8000 Series)

The Vectomag MK8000 Series Magneto Optical Kerr Effect (MOKE) Measurement System is a high-sensitivity instrument designed for precision magnetic characterization.

It enables direct measurement of longitudinal, transverse, and polar Kerr rotation angles or ellipticity, while simultaneously acquiring magnetic hysteresis loops including coercivity and saturation fields.

This system combines Kerr effect measurement and magnetic domain observation, providing researchers with the ability to analyze micro-magnetic behaviors, magnetic anisotropy, and domain evolution in real-time.
