In this paper, the magnetic properties of an individual square permalloy (Ni80Fe20) nanoelement at the center of an array with both in-plane shape anisotropy and interelement interaction were investigated by the 3-D object oriented micromagnetic framework. Variation of the interelement coupling was studied by changing the element lateral size (a) and interelement spacing (s). Magnetic hysteresis loop...
Miniaturization of the magnetic devices is highly recommended for achieving large areal density up to 1 Tbit/in2 in magnetic data storage. Recently, based on the bit patterned media (BPM) concept, nanomagnets have shown huge prospect in this aspect. For the BPM concept, the nanomag-nets-based logic and memory applications require a deterministic 180° switching of the magnetization, i.e. the nanomagnet...
The effect of an ultra thin NiO(11Å) capping layer on the temperature dependence of the interlayer coupling of a [Pt(26.5Å)/Co(4Å)] 3 multilayer with perpendicular anisotropy has been investigated. In the presence of the NiO(11Å) capping layer, the interlayer coupling between the Co layers has been observed to demonstrate interesting temperature-dependent transitions. Only the antiferromagnetic...
