要旨:
Noncollinear magnets provide essential ingredients for the next
generation memory technology. It is a new prospect for the Heusler
materials, already well known due to the diverse range of other
fundamental characteristics. Here, we present a combined experimental
and theoretical study of novel noncollinear tetragonal Mn2RhSn Heusler
material exhibiting unusually strong canting of its magnetic
sublattices. It undergoes a spin-reorientation transition, induced by a
temperature change and suppressed by an external magnetic field. Because
of the presence of Dzyaloshinskii-Moriya exchange and magnetic
anisotropy, Mn2RhSn is suggested to be a promising candidate for
realizing the Skyrmion state in the Heusler family.
