Abstract

Abstract: Mssbauer spectra of<superscript>57</superscript>Co-doped polycrystalline or single-crystal samples of layered perovskites La<subscript>2</subscript>Mo<subscript>4</subscript> (M=Cu, Co, Ni) and R<subscript>2</subscript>CuO<subscript>4</subscript> (R=Nd, Eu, Gd) were recorded at room temperature and below. Of the samples studied, only La<subscript>2</subscript>CuO<subscript>4</subscript> shows a widely separated doublet at room temperature and a single clearly resolved sextet well belowT <subscript>N</subscript>.
