Magnetotransport

Spin and current transport as well as thermodynamic and spincaloritronic properties of samples are often studied as a function of the applied magnetic field. For such measurements several superconducting magnets are available at the WMI.

Three of them (14 T, 16 T, and 15/17 T) are located in the high-field laboratory in the upper floor of the WMI.

Another 3D vector magnet with variable temperature insert, allowing for 2.5 T in-plane and 6 T out-of-plane magnetic fields, is available for thermal and electrical transport experiments since 2018. It contains a vertically oriented 6 T solenoid combined with two horizontally oriented split-coil pairs.

A further 3D vector magnet allowing for 1 T in-plane and 6 T out-of-plane magnetic fields is installed in the WMI Quantum Laboratories as part of a cryogen-free dilution system.
