Complex and strongly anisotropic magnetism in the pure spin system EuRh<sub>2</sub>Si<sub>2</sub>
In divalent Eu systems, the 4f local moment has a pure spin state J = S = 7/2. Although the absence of orbital moment precludes crystal electric field effects, we report a sizable magnetic anisotropy in single crystals of EuRh2Si2. We observed a surprisingly complex magnetic behavior with three successive …
