Spin-frustrated antiferromagnets based on BEDT-TTF and manganese dicyanamide complexes

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

“…Schlueter et al [14] did not find any evidence of a spin-glass state or spin frustrations in the crystals they investigated. In spite of the results of [14], in [15] …”

“…The sample under investigation and the reference sample were placed in a hermetically sealed silica glass tube in an argon atmosphere. 3 Spin frustrations in magnetic sublattice In [15] we showed antiferromagnetic correlations corresponding to the Weiss constant of −8 K in the studied crystals. The field dependence at T = 2 K is not similar to the Brillouin function as was expected for a paramagnetic sample with small exchange interaction (Fig.…”

“…4 Interaction of magnetic and conductive systems It was shown in [15] that a linewidth of Mn and BEDT-TTF subsystems cannot be due to exchange or dipole-dipole interactions. Thus, spin relaxation processes of paramagnetic particles mainly contribute to the linewidths.…”

“…1) are described in [15,16], in which the contributions of BEDT-TTF and Mn to the electron spin resonance (ESR) signal are distinguished and recognized.…”

“…Recently the synthesis and magnetic properties of a new spin-frustrated compound (BEDT-TTF) 2 Mn[N(CN) 2 ] 3 have been reported [14][15][16]. The Mn[N(CN) 2 ] 3 complexes forming a triangular planar lattice ( Fig.…”
