Effect of defects in Heusler alloy thin films on spin-dependent tunnelling characteristics of Co2MnSi/MgO/Co2MnSi and Co2MnGe/MgO/Co2MnGe magnetic tunnel junctions.
Fully epitaxial magnetic tunnel junctions (MTJs) with Co-based Heusler alloy Co(2)MnSi electrodes and a MgO tunnel barrier were fabricated with various values of Mn composition α for Co(2)Mn(α)Si in Co(2)Mn(α)Si/MgO/Co(2)Mn(α)Si MTJs. The tunnel magnetoresistance (TMR) ratios at both 4.2 K and room temperature (RT) increased systematically with increasing α in Co(2)Mn(α)Si electrodes from Mn-de...

متن کاملMagnetic and structural depth profiles of Heusler alloy Co2FeAl0.5Si0.5 epitaxial films on Si(1 1 1).
The depth-resolved chemical structure and magnetic moment of [Formula: see text], thin films grown on Si(1 1 1) have been determined using x-ray and polarized neutron reflectometry. Bulk-like magnetization is retained across the majority of the film, but reduced moments are observed within 45[Formula: see text] of the surface and in a 25[Formula: see text] substrate-interface region. The reduce...
متن کاملStructural properties of magnetic Heusler alloys
Magnetically driven actuator materials, such as the ternary and intermetallic Heusler alloys with composition X2YM, are studied within the density-functional theory (DFT) with the generalized gradient approximation (GGA) for the electronic exchange and correlation. The geometrical and electronic structures for the magnetic L21 structure are calculated. The structures and magnetic moments at equ...
