Magnetic frustration induced large magnetocaloric effect in the absence of long range magnetic order

Abstract We have synthesized a new intermetallic compound Ho2Ni0.95Si2.95 in a single phase with a defect crystal structure. The magnetic ground state of this material found to be highly frustrated without any long range order or glassy feature as investigated through magnetic, heat capacity and neu...
