摘要
The influence of dehydration on the electron spin resonance spectra in the Cu-3[W(CN)(8)](2)(pyrimidine)(2) center dot 8H(2)O molecular magnet has been found. It has been established that two ferromagnetic phases with the Curie temperatures of similar to 12-17 and similar to 50 K, which correspond to two different lines of the ferromagnetic resonance, are present in crystals. Dehydration leads to increasing the Curie temperature of the low-temperature phase from 12 to 17 K and to varying the temperature dependences of the spectrum parameters of the high-temperature phase (the resonant field and the width line).
