Jahn-teller induced random strain effects in TmPO4

Abstract

Random strain effects which arise from Jahn-Teller interactions and dominate the high-symmetry phase of cooperative Jahn-Teller systems are also important in TmPO4 although it does not undergo a cooperative Jahn-Teller phase transition. The EPR spectra of TmPO4(Gd3+) are analyzed in terms of these effects. © 1977 The American Physical Society.
