87Rb NMR study of the magnetic structure of the quasi-two-dimensional antiferromagnet RbFe(MoO4)2 on a triangular lattice

Abstract

87Rb nuclear magnetic resonance was experimentally studied in a quasi-two-dimensional Heisenberg antiferromagnet RbFe(MoO4)2. Dipole fields at the 87Rb nuclei were found over a wide range of temperatures and static magnetic fields. Magnetic structures in the ordered phase were determined at various magnetic fields.
