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 (χ) and heat capacity measurements showed the absence of long range magnetic ordering, at least down to 2 K. However, the χ 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 (-ΔSm) of 6.8 and 12.8 J/kg K and an adiabatic temperature change (ΔTad) of 3.8 K and 8 K at 2.85 K for magnetic field changes of 3 T and 9 T, respectively.
