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…
Scaling of the minimal step-step distance with the step-bunch size: Theoretical predictions and experimental findings (a mini-review)
Katarzyna Siewierska, Vesselin Tonchev
We review the studies on the scaling of the minimal step-step distance lmin in the bunch with the bunch size N, l_min~N^(-γ). We build our retrospective around the different values…
