Magnetism of noncolinear amorphous DyCo3 and TbCo3 thin films
Zexiang Hu, Ajay Jha, Katarzyna Siewierska +4
The magnetization of amorphous DyCo3 and TbCo3 is studied by magnetometry, anomalous Hall effect and magneto-optic Kerr effect to understand the temperature-dependent magnetic stru…
Magnetism, transport and atomic structure of amorphous binary YxCo1-x alloys
Zexiang Hu, Jean Besbas, Katarzyna Siewierska +3
Sputtered thin films of binary YxCo1-x with 0 < x < 0.54 and thickness 15 nm are investigated to help understand the ferromagnetism of cobalt in amorphous rare-earth cobalt alloys.…
Quasi-static magnetization dynamics in a compensated ferrimagnetic half-metal -- MnRuGa
Ajay Jha, Simon Lenne, Gwenael Atcheson +3
Exploring anisotropy and diverse magnetization dynamics in specimens with vanishing magnetic moments presents a significant challenge using traditional magnetometry, as the low res…
Phonon and magnon jets above the critical current in nanowires with planar domain walls
Maria Stamenova, Plamen Stamenov, Tchavdar Todorov
We show through non-equilibrium non-adiabatic electron-spin-lattice simulations that above a critical current in magnetic atomic wires with a narrow domain wall (DW), a couple of a…
Ab initio comparison of spin-transport properties in MgO-spaced ferrimagnetic tunnel junctions based on MnGa and MnAl
Maria Stamenova, Plamen Stamenov, Nadjib Baadji
We report on first-principles spin-polarised quantum transport calculations (from NEGF+DFT) in MgO-spaced magnetic tunnel junctions (MTJs) based on two different Mn-based Heusler f…
CoRuVSi: A potential candidate for spin semimetal with promising spintronic and thermoelectric properties
Jadupati Nag, R. Venkatesh, Ajay Jha +4
Based on our experimental and theoretical studies, we report the identification of the quaternary Heusler alloy, CoRuVSi as a new member of the recently discovered spin semimetals…
