چکیده انگلیسی
ⶠThe effect of the substitution of Cu for Ni on magnetoresistance and magnetocaloric properties of Ni50Mn34In16. As known well, the studies on the magnetocaloric materials for example Ni-based Heusler alloys have increasing attention in recently. We used two different measurements method for the measurements of M(H) curves: continuous and noncontinuous method to find the influence of irreversibility on magnetocaloric effect. We observed that the magnetic entropy change depends strongly on magnetization measurement methods. The Ni47.5Cu2.6Mn34.0In15.9 alloy shows the magnetostructural transition whose irreversible ratio is about 50% at 160 K. The magnetocaloric effect strongly depends on the sample history due to the occurrence of the irreversible magnetostructural transition. Giant magnetoresistance is about â68% that is the bigger than that of the bulk alloys for the magnetic field change of 2 T. We think that our study should be a good reference for the people who work about the magnetocaloric effect.
