Abstract
-
A nanostructured honeycomb lattice consisting of MnPS3 nanoparticles synthesized via the
ion-exchange technique was found to have restacked molecular layers stabilized by H2O
insertion between the layers. Susceptibility (v) and heat capacity measurements showed the
absence of long range magnetic ordering, at least down to 2K. However, the v data showed that
the system possesses a high effective Curie temperature, suggesting that the system is in a high
spin lattice disordered state. Evaluation of the magnetocaloric effect indicates that the system has
a large reversible magnetic-entropy change (DSm) of 6.8 and 12.8J/kg K and an adiabatic
temperature change (DTad) of 3.8K and 8K at 2.85K for magnetic field changes of 3 T and 9 T,
respectively.
