Electron paramagnetic resonance of Mn²⁺ in CuGaS₂

Abstract

The electron paramagnetic resonance of Mn 2+ has been observed in three different environments in CuGaS 2 . Designated Mn I , Mn II and Mn III , they are interpreted respectively as: (i) Mn 2+ ions substitutional at a Ga site: (ii) Mn 2+ ions substitutional at a Cu site; and (iii) Mn 2+ ions substitutional at a Cu site with a next-nearest-neighbour Cu vacancy.
