Abstract

Magnetic properties of Prussian blue analogues VIII[CrIII(CN)6] · 7H2O and (VIVO)3[CrIII(CN)6]2 · 4H2O are presented. M(T) dependence shows an increase of magnetisation below the paramagnetic Curie temperature Tcp = 107 K and Tcp = 167 K for the complexes with VIV and with VIII, respectively. Both compounds are ordered ferrimagnetically below the Curie temperature Tc = 53 K (VIV) and Tc = 88 K (VIII) determined by the Weiss method from M2 vs. T dependence. Experimentally found μS = 0.63μB (VIV) and μS = 0.91μB (VIII) corresponds well with the theoretical one. The irreversibility in FC and ZFC magnetisation was observed. The maxima in M(T) at Tmax = 16 K (sample VIV) and at Tmax = 32 K (sample VIII) at H = 10 Oe shift to lower temperatures and become less pronounced at higher magnetic fields. The H-dependence Tmax and bifurcation Tirr suggests a cluster glass behaviour. Both samples exhibit a strong electron paramagnetic resonance signal at g(VIII) = 1.84 and g(VIV) = 1.79 with the peak to peak linewidth ΔHpp(VIII) = 73 Oe and ΔHpp(VIV) = 944 Oe at room temperature.
