摘要
The influence of minor Pr substitution on the magnetocaloric effect (MCE) of Mn1-x Pr (x) As (x = 0.005, 0.01, 0.015, 0.02) alloys has been investigated. The lattice parameters a, c and unit cell volume V of the alloys Mn1-x Pr (x) As (x = 0.005, 0.01, 0.015, 0.02) increase monotonically with increasing Pr content. The Pr addition has minor effect on tuning the Curie temperature T (c) from 318 K to 321 K for x = 0.005-0.02 and reducing the thermal hysteresis (about 20 K). With increasing the temperature, the critical field induced paramagnetic (PM)-ferromagnetic (FM) transition shifts to higher values. The Pr substitution makes the paramagnetic phase unstable and stabilizes the ferromagnetic phase, which lead to increasing in Curie temperature T (c) of Mn1-x Pr (x) As (x = 0.005, 0.01, 0.015, 0.02) alloys. The absence of the huge magnetic entropy change spike which was calculated by the Maxwell relation is observed in the temperature range where the stepwise magnetic behaviors occur. The Clausius-Clapeyron equation is used to recalculate the of alloys Mn1-x Pr (x) As (x = 0.005, 0.01, 0.015, 0.02) under the conditions of the coexistence of the PM and FM phases. The maximum magnetic entropy change of alloys Mn1-x Pr (x) As (x = 0.005, 0.01, 0.015, 0.02) for a 5 T field change decreases gradually from 30.2 J/kg K to 23.3 J/kg K as Pr increases from 0.005 to 0.02.
