Probing the angular dependence (i.e. anisotropy) of the electrical resistance provides key insights into the electronic and crystallographic properties of materials. The Horizontal Rotator enables a sample to be rotated over 360° in the presence of an applied magnetic field. An automated indexing procedure and encoder ensures accurate angular positions and the on-board thermometer monitors the temperature in close proximity to the sample Materials chosen to minimize magnetic and temperature effects to ensure reproducibility upon cycling environmental parameters. Two types of sample boards provided, one where the rotation axis remains in the sample plane, and one where the axis points out of the sample plane. Two channels per sample board, each channel provides 4-probe electrical contacts.

The rotator option allows the sample to be rotated around a horizontal axis in the presence of an applied magnetic field. The magnetic field is on the vertical axis, or z axis. The turning range is from -10°to 370°, with a pitch of 0.0133°. The 0° angle corresponds to the magnetic field perpendicular to the measurement platform.




This option will allow to characterize mainly the anisotropic response of the electrical transport in materials, as is the case of the measurement of the magnetoresistance anisotropy (AMR), critical current in superconductors, etc., in addition to being able to perform anisotropic magnetocaloric effect measurements.
