An electron paramagnetic resonance (EPR) study of Er<Superscript>3+ </Superscript> ions in single crystals of RbTiOPO<Subscript>4</Subscript> (RTP) is presented. The EPR spectra show the existence of six different Er<Superscript>3+</Superscript> centres. The g-matrix has been determined for these centres from the analysis of the angular dependences of the spectrum in...</superscript></subscript></superscript>
