Effect of Mn²⁺ spin frustrations on spin dynamics of charge carriers in (BEDT‐TTF)₂Mn[N(CN)₂]₃ crystals

Abstract

The effect of spin frustrations of Mn2+ planar lattice on the spin relaxation rate in conductive BEDT‐TTF layers was observed. Layer‐to‐layer exchange availability was proved. Critical field of spin flop transition Hc = 32 kOe measured in our experiments makes it possible to estimate the interplanar exchange interaction as ∼10–3 K. Indirect interplanar exchange occurs through BEDT‐TTF layers due to spin polarization of conducting band electrons contributing to the exchange interaction. (© 2008 WILEY‐VCH Verlag GmbH & Co.
