Dinuclear molecular magnets with unblocked magnetic connectivity: magnetocaloric effect.

ABSTRACT: A detailed study of the magnetocaloric effect in two isostructural bimetallic compounds {[M^II(H₂O)₂]₂[Nb^IV(CN)₈]·4H₂O} _n (M = Mn, Fe) is presented. The substances show sharp phase transitions to the long-range magnetically ordered state with ferromagnetic coupling between M and Nb sublattices in the case of the Fe-based sample (FeNb, T _c = 43 K) and antiferromagnetic coupling for the Mn-based sample (MnNb, T _c = 50 K). The magnetic entropy change was found to reach 5.07 J mol^-1 K^-1 (9.09 J kg^-1 K^-1) for MnNb and 4.82 J mol^-1 K^-1 (8.65 J kg^-1 K^-1) for FeNb under the applied m
