Abstract

The temperature dependence of the EPR spectrum of Cu2+ in the range 293–393 K exhibits a low-spin (S=0) to high-spin (S=2) transition of the Fe2+ ions, with hysteresis (T c↑=363 K,T c↓=343 K). At 103 K, the principal values of theg and hyperfine tensors of Cu2+ ions are revealed by hyperfine structure.
