Abnormal magnetic behaviors and large magnetocaloric effect in MnPS3 nanoparticles

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.
