A trigon structure formed by submonolayer gadolinium deposition onto Au(111) is revealed as a robust growth template for Co nanodot arrays. Scanning Tunneling Microscopy and X-Ray Magnetic Circular Dichroism measurements evidence that the Co nanoislands behave as independent magnetic entities with an out-of-plane easy axis of anisotropy and enhanced magnetic anisotropy values, as compared to ot...

The influence of winding-induced mechanical stresses on the magnetic anisotropy and core loss in toroidal cores made of Fe73Cu1Nb3Si16B7 ribbon is studied. The ribbon for the cores was rapidly pre-heated under tensile stress up to 120 MPa. It was found that magnetic characteristics of the material (magnetic anisotropy energy and the core loss) can be controlled by varying the tensile stress dur...

Using first-principles calculations, we predict that the magnetic anisotropy energy of Co-doped TiO2 sensitively depends on carrier accumulation. This magnetoelectric phenomenon provides a potential route to a direct manipulation of the magnetization direction in diluted magnetic semiconductor by external electric-fields. We calculate the band structures and reveal the origin of the carrier-dep...

Performing state-of-the-art ab initio calculations we study the effect of the electric field on magnetic properties of Co and Co-Pt chains on Pt(111). Our studies give clear evidence that an externally applied electric field could permit one to tailor magnetic anisotropy in chains. It is demonstrated that the physics behind this effect is related to the spin-dependent screening of an external e...

Growing of epitaxial Fe50Mn50/Fe/Mo/R-sapphire films was performed with a new configuration of two in-plane easy axes of Fe(001)-layer magnetization in which application of annealing in a magnetic field forms an unidirectional anisotropy. The microstructures made from these films exhibited an exchange bias 25-35 G along an exchange field generated at antiferromagnet/ferromagnet (AFM/FM) interfa...

Theory of magnetoresistance in films of dilute magnetic alloys. Abstract Giordano measured the magnetoresistance of dilute magnetic alloys Au(Fe) films of different thickness. He explained the difference in the magnetic field saturation for different thickness by the magnetic surface anisotropy for the impurities has been suggested and evaluated earlier, which is due to spin-orbit scattering in...

The effect of magnetic shaking on both the transverse and axial shielding factors ~TSF and ASF! is investigated using open-ended cylindrical shields made of Metglas 2705M amorphous ribbons. Shaking enhancement is found to be strongly dependent on the orientation of the magnetic anisotropy of the shielding material, that is, the anisotropy axis should be aligned along the corresponding shielding...

Highly uniform and well-aligned one-dimensional Ni nanochains with controllable diameters, including 33, 78, and 120 nm, have been synthesized by applying an external magnetic field without any surface modifying agent. The formation can be explained by the interactions of magnetic dipoles in the presence of applied magnetic field. Magnetic measurements demonstrate that the shape anisotropy domi...

Flexible, uniform and surface smooth iron-based metallic glassy fibers (MGFs) were fabricated by a melt-extraction method. There was large magnetic anisotropy in the MGF. Our experimental results indicated that this large magnetic anisotropy was related to the unique magnetic domain structures in the MGF.
