Field application configurations

4-Pole Magnet

  • 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

Perpendicular Coil

  • 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

Perpendicular Electromagnet

  • 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

Single Sheet Magnet

  • 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
Temperature Manipulation

Cryo-stage

  • 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

Optical heating stage

  • 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
