Study of magnetocaloric effect in off stoichiometric ni mn sb heusler compounds by density functional theory and monte carlo methods

Abstract

Solid state cooling or heating using magnetocaloric materials has emerged as an energy efficient green technology The magnetocaloric effect MCE describes the thermal response of a magnetic material due to the application of a magnetic field which is quantified by isothermal magnetic entropy change 206 8221 S mag and the adiabatic temperature change 206 8221 T ad An extended search of new magnetocaloric materials exhibiting giant MCE in an appropriate temperature range as well as improving performa...
