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.…
Effects of disorder on the magnetic properties of the Heusler alloy VFeAl
Ross Smith, Zsolt Gercsi, Rui Zhang +3
Magnetic properties of multicomponent alloys depend sensitively on the degree of atomic order on the different crystallographic sites. In this work we demonstrate the magnetic cont…
RuMnAl thin films
K. E. Siewierska, H. Kurt, B. Shortall +7
The cubic Heusler alloy RuMnAl is grown in thin film form on MgO and MgAlO substrates. It is a highly spin-polarised ferrimagnetic metal, with weak magnetoc…
Stability of Mn2RuxGa-based Multilayer Stacks
Gwenael Atcheson, Katarzyna Siewierska, J. M. D. Coey +2
Perpendicular heterostructures based on a ferrimagnetic Mn2RuxGa (MRG) layer and a ferromagnetic Co/Pt multilayer were examined to understand the effects of different spacer layers…
Magnetic reversal and pinning in a perpendicular zero moment half-metal
Niclas Teichert, Gwenael Atcheson, Katarzyna Siewierska +6
Compensated ferrimagnets are promising materials for fast spintronic applications based on domain wall motion as they combine the favourable properties of ferromagnets and antiferr…
Magnetic order and magneto-transport in half-metallic ferrimagnetic MnRuGa thin films
K. E. Siewierska, G. Atcheson, A. Jha +8
The ruthenium content of half-metallic MnRuGa thin films, with a biaxially-strained inverse Heusler structure, controls the ferrimagnetism that determines their magnetic an…
Single pulse all-optical toggle switching of magnetization without Gd: The example of Mn2RuxGa
C. Banerjee, N. Teichert, K. Siewierska +6
Energy-efficient control of magnetization without the help of a magnetic field is a key goal of spintronics. Purely heat-induced single-pulse all-optical toggle switching has been…
Study of the Effect of Annealing on the Properties of Mn2RuxGa Thin Films
K. E. Siewierska, G. Atcheson, K. Borisov +3
The effect of vacuum annealing thin films of the compensated ferrimagnetic half-metal Mn2RuxGa at temperatures from 250 to 400 degree Celsius is investigated. The 39.3 nm films dep…
Imaging Domains in a Zero-Moment Half Metal
K. E. Siewierska, N. Teichert, R. Schäfer +1
We have a choice of methods for examining domains at the surface of a ferromagnet that depend on probing the stray field distribution, but these methods do not work in antiferromag…
