A number of options and extensions are available for the two evico magnetics Kerr microscope systems.

• Computer controlled rotating magnetic field (manual control with hand-wheel on control panel is also possible)

• For in-plane magnetic field

• Superposition of DC and AC fields at different angles

• Supported on a magnet holder with adjustable height, independent from sample holder

• Water-cooled

• Generates magnetic field perpendicular to the sample surface (i.e. along direction of objective axis)

• Field strength up to 950 mT

• Supported on magnet holder with adjustable height, independent from sample holder

• Water-cooled

• Generates magnetic field along the direction of the objective axis

• Field strength up to 100 mT

• Supported on magnet holder with adjustable height, independent from sample holder

• Water-cooled

• Magnetization stage for domain observation in electrical steel sheets in Epstein geometry (30 x 300 mm, sheet thickness variable) and amorphous and nanocrystalline ribbons of usual geometry

• Flux closure by laminated yoke

• In-situ application of tensile stress up to 100 MPa

• Pickup coil for measurement of AC hysteresis loop

The cryo- and heating systems can be obtained separately or in a package. In case of the package, some additions can be jointly used.

• Temperature range: 4 K - 325 K

• Especially adapted for the needs of Kerr microscopy: the sample is fixed by thermally conductive glue on an elongated cooling finger

• Observation through a glass window

• Cryostat can be used together with evico magnetics rotatable ("standard") magnet and perpendicular coil

• Sample size: < 9 mm circular diameter

• Stage table, xy-shift by approx. ± 5 mm

• Long distance objective lenses (20x - 50x, corrected for glass window)

• Additions: temperature measurement and regulation system, isolation vacuum pumping system, liquid gas transfer line, vibration-damped pump stand etc

• Temperature range: 300 K - 890 K

• Especially adapted for the needs of Kerr microscopy: the sample is mechanically fixed on an elongated heating finger

• Observation through a glass window

• Stage can be used together with evico magnetics rotatable ("standard") magnet and perpendicular coil

• Sample size: < 9 mm circular diameter

• Stage table, xy-shift by approx. ± 5 mm

• Long distance objective lenses (20x - 50x, corrected for 1 mm glass)

• Additions: temperature measurement and regulation system, isolation vacuum pumping system, liquid gas transfer line, vibration-damped pump stand etc

• Special tool in the software, designed for the semi-automatic determination of the (main) orientation angles of individual grains in Goss-textured FeSi transformer steel by domain analysis

• Non-magnetic lenses with strongly reduced ferromagnetic components
