The influence of alloying on the stacking fault energy of gold from density functional theory calculations
Anuj Goyal, Yanzhong Li, Aleksandr Chernatynskiy +4
The generalized stacking fault (SFE) energy curves of pure gold (Au) and its binary alloys with transition metals are determined from density functional theory (DFT). Alloy element…
Extraordinary temperature dependent magnetic anisotropy of the non-collinear antiferromagnet IrMn
Sarah Jenkins, Roy Chantrell, Timothy Klemmer +1
The magnetic anisotropy of antiferromagnets plays a crucial role in stabilising the magnetisation of many spintronic devices. In non-collinear antiferromagnets such as IrMn the sym…
First order reversal curves and intrinsic parameter determination for magnetic materials; limitations of hysteron-based approaches in correlated systems
Sergiu Ruta, Ondrej Hovorka, Pin-Wei Huang +3
The generic problem of extracting information on intrinsic particle properties from the whole class of interacting magnetic fine particle systems is a long standing and difficult i…
Atomistic origin of exchange anisotropy in -IrMn-CoFe bilayers
Sarah Jenkins, Wei Jia Fan, Roxana Gaina +3
The exchange interaction determines the ferromagnetic (FM) or antiferromagnetic (AFM) ordering of atomic spins. When ferromagnets and antiferromagnets are coupled together, they of…
The 2014 Magnetism Roadmap
Robert L. Stamps, Stephan Breitkreutz, Johan Åkerman +11
Magnetism is a very fascinating and dynamic field. Especially in the last 30 years it has experienced many major advances in the full range from novel fundamental phenomena to new…
Magnetic anisotropy of Fe_1-yX_yPt-L10 [X=Cr,Mn,Co,Ni,Cu] bulk alloys
R. Cuadrado, Timothy J. Klemmer, R. W. Chantrell
We demonstrate by means of fully relativistic first principles calculations that, by substitution of Fe by Cr, Mn, Co, Ni or Cu in FePt-L10 bulk alloys, with fixed Pt content, it i…
