Ferromagnetic thin films with moderate perpendicular magnetic anisotropy (PMA) are known to support weak stripe domains provided film thickness exceeds a critical value. In this work, we performed both an experimental and theoretical investigation of

In thin magnetic films with perpendicular magnetic anisotropy, a periodic “up-down” stripe-domain structure can be originated at remanence, on a mesoscopic scale (~100 nm) comparable with film thickness, by the competition between short-range exc

Robustness of majority gates based on nanomagnet logic

Autor: Himadri Dey, Marco Gonelli, György Csaba, Diego Bisero, Samuele Fin, Wolfgang Porod, Gary H. Bernstein, Giovanni Carlotti

We studied the evolution of the magnetic state of a majority logic gate consisting of a cluster of five dipolarly-coupled nanomagnets, fabricated by e-beam lithography, under the application of a clocking field, using a combination of magneto-optical

In this work we show the development of bulk in-plane magnetic anisotropy in high Ga-content (Ga = 28 at. %) Fe100-xGax thin films as the layer thickness increases. This result is in clear contrast with the generally reported decrease of this anisotr

The magnetic properties of an iron nitride thin film obtained by ion implantation have been investigated. N[Formula: see text] ions were implanted in a pristine iron layer epitaxially grown on ZnSe/GaAs(001). X-ray diffraction measurements revealed t

The interest in Tb-Fe-Ga alloys, prepared by techniques compatible with technological processes, has been increasing in the last years, due to their high magnetostriction combined with their potential application in spintronic devices. In this letter

We report the magnetic anisotropy and domain configuration of cosputtered TbFeGa alloys. The layers were deposited from two targets with compositions TbFe2 and Fe3Ga, respectively. The structural and magnetic properties do not only depend on the comp

TbxFe_(73)Ga_(27-x) (7 at.% ≤ x ≤ 11 at.%) ternary alloys have been obtained by cosputtering from Tb_(33)Fe_(67) and Fe_(72)Ga_(28) targets. In contrast with other Tb-Fe-Ga compounds that consist of just one structural phase, the diffraction patt
