The Magnetocaloric Effect of Nonstoichiometric ErM2Mnx Compounds (with M = Ni, Co, and Fe)

The structure and magnetic and magnetocaloric properties of nonstoichiometric ErM 2 Mn x alloys with M = Ni, Co, and Fe have been studied. ErNi 2 Mn x alloys with x ≤ 1.25, ErCo 2 Mn x alloys with x ≤ 0.8, and ErFe 2 Mn x alloys with x ≤ 0.4 are shown to solidify with the formation of the cubic MgCu...

Zusammenfassung:The structure and magnetic and magnetocaloric properties of nonstoichiometric ErM 2 Mn x alloys with M = Ni, Co, and Fe have been studied. ErNi 2 Mn x alloys with x ≤ 1.25, ErCo 2 Mn x alloys with x ≤ 0.8, and ErFe 2 Mn x alloys with x ≤ 0.4 are shown to solidify with the formation of the cubic MgCu 2 -type structure. The magnetocaloric effect of the ErM 2 Mn x compounds is estimated based on magnetic measurements and using the thermodynamic Maxwell’s relation. The ErFe 2 Mn 0.4 compound is found to demonstrate a plateau-like temperature dependence of the magnetic entropy change over the wide temperature range from 77 to 300 K.
