We investigate the incorporation of manganese into self-catalyzed GaAs nanowires grown in molecular beam epitaxy. Our study reveals that Mn accumulates in the liquid Ga droplet and that no significant incorporation into the nanowire is observed. Usin

Co2MnGe films of 30 and 50 nm in thickness were grown by RF-sputtering. Their magnetic anisotropies, dynamic properties and the different excited spin wave modes have been studied using conventional ferromagnetic resonance (FMR) and Microstrip line F

Recent discoveries of phenomena that relate electronic transport in solids to the spin angular momentum of the electrons are the fundamentals of spin electronics (spintronics). The first proposed conceptual spintronic device, the spin field-effect tr

Thin GaMnAs layers were grown by low temperature molecular beam epitaxy on (0 0 1), (3 1 1) A and (1 1 0) GaAs substrates. In an effort to increase the ferromagnetic transition temperature TC, we studied growth conditions and the effectiveness of pos

The magnetic anisotropy of thin Fe films on (001)-oriented GaAs has been investigated using the fully relativistic TB-KKR method of band structure calculation. In line with experimental findings an in-plane anisotropy has been found with the easy axi

The magnetic properties of disordered layered structures grown on surface-reconstructed substrates are studied with respect to percolation and random fields phenomena. Both the layered site-dilution and fluctuating magnetic field are considered in th

The thickness dependence of the fourfold in-plane magnetic anisotropy was first observed in epitaxial Fe(001) films and described by the volume anisotropy of bcc Fe with a positive anisotropy constant (K1vol>0) superimposed by a negative interface te

Magnetic tunnel junctions in the sub-micrometre range have been patterned by electron beam lithography. The hard reference electrode is composed of an artificial antiferromagnetic subsystem while the soft magnetic detection layer is Permalloy (NiFe).

We have studied the ferrimagnetic spin-1 AB1AB2 superlattice in the presence of perpendicular single-ion anisotropy (Blume–Capel model) to have a direct evidence of the existence of multicompensation and tricritical effects. We present the theory b
