Effect of pressure on the magnetic properties of LiCuFe and LiCuFe@LiNiCr Prussian blue analogues

The effect of pressure on the magnetization of LiCuFe@LiNiCr Prussian blue analogue core@shell particles (inset, scale: 100 nm) is measured up to ≈1.4 GPa. A decrease in magnetization is observed with increasing pressure together with two transition temperatures, Tclow=20KandTchigh=70K corresponding to the ordering of the LiCuFe-PBA core and LiNiCr-PBA shell, respectively. The results indicate a robust Tclow at all pressures. On the other hand, a decrease in Tchigh is measured at pressures above 1.0 GPa.
