Abstract

Magnetization, magnetic torque, neutron diffraction and NMR experiments are used to map out the $H$ $-$ $T$ phase diagram of the prototypical quasi-two-dimensional ferro-antiferromagnet Pb $_2$ VO(PO $_4$ ) $_2$ in magnetic fields up to 27 T. When the field is applied perpendicular to the axis of magnetic anisotropy, a new magnetic state emerges through a discontinuous transition and persists in a narrow field range just below saturation. The measured NMR spectra suggest a complex and possibly incommensurate magnetic order in that regime.
