摘要：

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 up arrow = 363 K, T-c down arrow = 343 K). At 103 K, the principal values of the g and hyperfine tensors of Cu2+ ions are revealed by hyperfine structure.
