被引用回数:21 パーセンタイル:72.6(Physics, Multidisciplinary)Fermi surfaces and magnetic properties of an antiferromagnet EuBi were investigated on a flux-grown single crystal. A critical magnetic field of 225 kOe where the magnetic moments are forced to align ferromagnetically was well explained by the magnetic exchange interaction based on a two-sublattice model. The Fermi surface characteristics are in agreement with the theoretical prediction indicating a fully magnetic divalent state in Eu atoms.
