Magnetic and magnetocaloric properties of Ho3Ni1.05Ge2.1 alloy
Source abstract
Abstract
This study deals with the magnetic and magnetocaloric properties of Ho 3Ni 1.05Ge 2.1 alloy. This alloy consists of HoNiGe and Ho 2Ni 0.8Ge 1.2 phases, with the former exhibiting an antiferromagnetic transition at 5 K and the latter showing a complex magnetic ordering at 34 K, respectively. Isothermal magnetization studies also indicated the presence of metamagnetic transition at 2 K confirming the presence of antiferromagnetic components below 5 K. The alloy demonstrates a relative cooling power (RCP) of 264 J/kg and 602 J/kg at applied magnetic fields of 5 T and 9 T, respectively. These findings indicate that the Ho 3Ni 1.05Ge 2.1 alloy is a pertinent magnetocaloric material suitable for low-temperature applications.
