The uniform motion of chiral magnetic skyrmions induced by a spin-transfer torque displays an intricate dependence on the skyrmions' topological charge and shape. We reveal surprising patterns in this dependence through simulations of the Landau-Lifs

In this work, we show the possibility of tuning the domain wall dynamics in amorphous ferromagnetic microwires by means of thermal annealing. We investigate the effect of annealing time and temperature on the field dependence of the domain wall veloc

The effect of the deposition temperature (Tdep) on the crystallographic orientation of pulsed laser-deposited FeCo/MgO(100) thin film was determined by means of X-ray reflectivity and high resolution trasmission electron microscopy analysis and was c

We obtained almost clean samples of binary system solid solutions (1 − x)BiFeO3-xPbTiO3 (0.1 ≤ x ≤ 0.5, Δx = 0.1) using the solid-state reaction technique with further sintering according to common ceramic technology. We studied the formation

Publikováno v: physica status solidi (a). 211:1083-1086

We studied magnetic and thermal properties of Fe- and Co-based glass-coated microwires. The change of the specific heat near the Curie point, ΔCp, has been evaluated from the temperature dependence of the heat capacity obtained by the ratio-method w
