摘 要:The magnetic properties of Ho_(6)MnBi_(2)and Ho_(6)FeBi_(2)crystals are investigated by means of density functional *** materials are currently an active subject of research in the context of magnetic refrigeration applications since they exhibit a remarkable magnetocaloric *** this work,the equation of state,density of states and magnetic moments are calculated and compared with previous experimental results for these ***,the Curie temperatures for the paramagnetic to ferromagnetic phase transition observed in these systems are calculated from first *** the calculated quantities are in reasonable agreement with experimental data,which suggests that density functional theory could provide a reliable framework to theoretically investigate the magnetic properties of intermetallic ternary compounds.
