摘要:
We report on the observation of a temperature and field dependent anomalous Nernst effect (ANE) in a Ni-rich bulk Ni-Co-Mn-Sn full Heusler alloy. A large change in the transverse Nernst coefficient (N) is obtained across the first order magneto-structural transition from a tetragonal martensite to a cubic austenite phase. The saturation fields of both the ANE and the magnetization appear to depend largely on the magnetic anisotropy of the device. Such a change in the Nernst co-efficient may prove to be useful for switching applications controlled by temperature and magnetic field changes. Published by AIP Publishing.
