| Abstract: | Ferrimagnetic resonance spectra of the Mn{(R/S)-pn}]2Mn{(R/S)-pn}]2(H2O)]Cr(CN)6]2 molecular magnetics were examined. It was established that, within the high-temperature (paramagnetic) region (T > 53 K), the EPR spectrum features a single Lorentz-shaped peak, while, at temperatures below 53 K, in a three-dimensional ferrimagnetic state, this peak splits into several components, some of which correspond to different states of spins in the helical chains of atoms comprising the chiral crystalline structure. |
