Abstract

The investigation of magnetization and anisotropic Hall effect for single crystals of Nd₂Mo₂O₇ was reported. The investigation was done under high magnetic fields up to 27 T and at low temperatures down to 59 mK. It was found that the Nd moments with strong Ising anisotropy were coupled antiferromagnetically with the Mo spins and show field-induced flipping on the respective sites.
