abstract = {Melt spun ribbons (MSR) of the Ni55Fe20Al25 alloy exhibit a first-order martensitic transition (MT) in the vicinity of a second-order ferromagnetic-to-paramagnetic phase transition.
Contrasted with a sharp, complete and thermoelastic MT in MSR, a partial, sluggish and nonthermoelastic MT occurs in annealed Ni55Fe20Al25 alloy that possesses a much higher degree of atomic order. However, the annealed samples have stronger local magnetocrystalline anisotropy and higher Curie temperature (TC) than MSR. Negative magnetoresistance, ∆ρ|| / ρ, is two times larger in MSR than in the annealed case. ∆ρ|| / ρ vs. H isotherms in MSR change curvature from concaveupwards to concave-downwards as the temperature is raised through TC whereas concavedownward curvature persists over the entire temperature range in the annealed counterpart.},
