摘要：

Mn2+-doped Fe(CIO4)2·6H2O, Co(ClO4)2·6H2O, and Ni(ClO4)2·6H2O have been studied by EPR from room temperature to liquid nitrogen temperature. Mn2+ replaces the metal ions at sites of trigonal symmetry. The EPR lines are broad and the D parameters are small; thus, there is considerable overlap in the spectra. The spectra are nearly axially symmetric. The temperature variation study shows phase transitions at 237 ± 5, 154.5 ± 6.5, and 223 ± 5 K in iron, cobalt, and nickel perchlorate hexahydrates, respectively. © 1979.
