Abstract
The singlet ground state antiferromagnet RbFeBr3 shows an induced moment behavior at low temperatures and orders antiferromagnetically at TN=5.5 K. A second magnetic phase transition takes place at 2.0 K. The magnetic phase between 2 K <TTQ(1/3,1/3,1) show a switching of intensity at 2 K. Above 4 K the magnetic excitations start to broaden. Above TN the magentic excitations show a renormalization behavior. The temperature dependence of renormalization is well described by the theoretical predictions of the DCEFA model.This publication has 0 references indexed in Scilit:
