Anisotropy of magnetocaloric effect and rotating magnetocaloric effect in 2D coordination polymer based on {CuII[WV(CN)8]}- and adeninium cations

Anisotropy of conventional magnetocaloric effect (MCE) and rotating magnetocaloric effect (RMCE) have been investigated in quasi-two-dimensional coordination polymer (AdeH){Cu-II[W-V(CN)(8)]}.2H(2)O with high magnetic anisotropy and topological phase transition. Magnetic entropy changes (delta Smag) were calculated from magnetic measurements of single crystals in three orthogonal directions, H||a*, H||b and H||c. The highest delta Smag = 3.49 J K-1 kg(-1) was recorded for conventional MCE in the H||c direction for mu 0|delta H|=7.0 T and at a peak temperature of 37.5 K. The RMCE was calculated for the rotation around the b axis by 90 from H||a* to H||c with the maximal delta Smag of 1.62 J K-1 kg (-1) detected for mu 0H = 7.0 T at 38 K.

This study investigates the anisotropy of conventional magnetocaloric effect (MCE) and rotating magnetocaloric effect (RMCE) in a quasi-two-dimensional coordination polymer (AdeH){Cu-II[W-V(CN)(8)]}.2H(2)O with high magnetic anisotropy and topological phase transition. The highest magnetic entropy change (delta Smag) of 3.49 J K-1 kg(-1) is observed for conventional MCE in the H||c direction at mu 0|delta H|=7.0 T and a peak temperature of 37.5 K. For the rotation around the b axis by 90 from H||a* to H||c, the maximal delta Smag of 1.62 J K-1 kg (-1) is detected at mu 0H = 7.0 T and 38 K.
