EPR Studies of Mn 2+ -Doped Diammonium Hexaaqua Magnesium(II) Sulfate

Abstract

Electron paramagnetic resonance (EPR) studies of Mn 2+ impurity in single crystals of diammonium hexaaqua magnesium(II) sulfate have been carried out at 9.3 GHz (X-band) at room temperature. The EPR spectra exhibit a group of five fine structure transitions. The spin-Hamiltonian parameters were determined. Mn 2+ enters the lattice interstitially. The EPR spectrum of a powder sample supports the data obtained by single crystal studies
