Abstract

Dy³⁺ doped SrLaGaO₄ exhibits unusually slow relaxation of magnetization determined by two widely separated excited Kramers doublets with a second remagnetization energy barrier of 223 cm^-1. This value considerably exceeds that for analogous Ca(Y,Dy)AlO₄ in spite of the apparently enlarged Dy³⁺ coordination sphere.
