Effect of short-range order on magnetic and transport properties of Fe 2 MnGa Heusler alloy films
Source abstract
Abstract
Abstract Fe 56 Mn 20 Ga 24 , Fe 46 Mn 35 Ga 19 and Fe 39 Mn 25 Ga 36 Heusler alloy (HA) films are investigated. It is shown that as-deposited Fe-Mn-Ga films are fine crystalline with a body-centered cubic (BCC) structure. Annealing of the films leads to the formation of a face-centered cubic (FCC) structure. The BCC to FCC transformation results in a drastic increase in the magnetization, the Curie temperature as well as in a change of the sign of temperature coefficient of resistivity from negative to positive. These effects are discussed in terms of band structures of L2 1 and L1 2 phases of stoichiometric Fe 2 MnGa HA.
