Pre-saturation phase in the frustrated ferro-antiferromagnet Pb $_{2}$ VO(PO $_{4}$ ) $_{2}$

arXiv:2006.04592 · doi:10.1103/PhysRevB.102.094414

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.
