Magnetic Microscopy

Responsible: Dr. Lars Bocklage - FS-PS

Physical and Magnetic Sample Characterization

The DESY NanoLab offers access to an Evico Magnetics Optical Kerr microscope:

Magneto-Optical Domain Imaging and Magnetometry


Measurement of magnetic hysteresis of thin films, micro- and nanoelements.

Magnetic domain imaging of thin films, micro- and nanoelemente



Reflection geometry

Objectives with magnification: 20x, 50x, and 100x

Optical resolution: 300 nm

Magneto-optical Kerr effect: Polar, longitudinal and transversal MOKE contrast


Sample Environment

Typical sample sizes < 35 mm

Piezo-based drift correction to improve magnetic domain imaging


Magnetic Field Options

Quadrupole magnet for in-plane magnetic fields up to 700 mT depending on sample size

Perpendicular coil for out-of-plane magnetic fields up to 100 mT

DC and AC magnetic field modes


Post Processing

Software for magnetic hysteresis curve evaluation
