Ferromagnetism in tetragonally distorted LaCoO3 thin films

Ferromagnetism in inhomogeneous Zn1−xCoxO thin films

We report on a systematic study of structural, optical, electrical, and magnetic properties of Zn1−xCoxO x=0.05–0.29 thin films codoped with Al 0.1% . Both codoped in which Co is cosputtered with other elements and -doped in which Co is doped digitally in the host matrix samples have been prepared and studied. Prior to doping of Co, growth conditions were optimized to produce ZnO:Al films with ...

Quantum-well-induced ferromagnetism in thin films

Ferromagnetism in nanocrystalline epitaxial Co:TiO2 thin films

Perpendicular magnetocrystalline anisotropy in tetragonally distorted Fe-Co alloys.

We report on the experimental realization of tetragonal Fe-Co alloys as a constituent of Fe0.36Co0.64/Pt superlattices with huge perpendicular magnetocrystalline anisotropy energy, reaching 210 microeV/atom, and a saturation magnetization of 2.5 microB/atom at 40 K, in qualitative agreement with theoretical predictions. At room temperature the corresponding values and are achieved. This suggest...

Ion-irradiation-induced ferromagnetism in undoped ZnO thin films

We have introduced defects in ZnO epitaxial thin films by swift heavy Ag ion irradiation and investigated systematically their magnetic, electrical and optical properties. Oxygen annealed ZnO films are epitaxial single crystals that exhibit no long-range magnetic order. However, in this paper it is shown that room-temperature ferromagnetism (RTFM) can be introduced in a controlled manner in the...
