The macroscopic properties of a magnetic material (hysteresis, energy loss, magnetic noise, etc) are determined by its magnetic microstructure, i.e. by magnetic domains and their reaction to magnetic field excitation. Therefore domain observation is essential for the development of magnetic materials and understanding of magnetization processes.

The evico magnetics Kerr Microscope & Magnetometer systems are facilities for the visualisation of magnetic domains and magnetization processes as well as for optically recording magnetization curves on all kinds of magnetic materials, including bulk specimens like sheets or ribbons, magnetic films and multilayers, patterned films or micro- and nanowires. They are semi-automatic, contact-less, non-destructive measuring systems using the magneto-optical Kerr effect (MOKE) as contrast mechanism.
