Angle-dependent Characterizations of Materials at mK Temperatures
The group of Anne de Visser at the Van der Waals- Zeeman Institute( University of Amsterdam, Netherlands) used attocubes rotators and benefitted from the“ quasi rotation” of a 1D magnet in two different approaches – rotating a small sample within limited space with an ANR51 and rotating a dilatometer inside a dilution cryostat by using an ANRv220.

Transition from Slow Abrikosov to Fast Moving Josephson Vortices
Cutting-edge application using the ANR31 rotator: The group of Bertram Batlogg( ETH Zurich, Switzerland) observed the formation of fast moving Josephson vortices, which depends critically on the angular alignment. Using an ANR31, they were able to rotate the sample below 2 K with better than 0.1 ° precision and could observe no drifts while sweeping temperature and magnetic field.

Cryogenic Angle-dependent Magnetoresistance Measurement
Christian Butschkow and co-workers from the group of Dieter Weiss( University of Regensburg, Germany) measured magnetotransport on individual GaAs /( Ga, Mn) As core-shell nanowires. An atto3DR allowed them to align the nanowires exactly to the 1D magnetic field. Their results showed the resistance anisotropy being dominated by the effective magnetic field and a relation between the origin of the NMR and the spin scattering.
