Configurational spin reorientation phase transition in magnetic nanowire arrays

“…The crossover occurs at a volume ratio of 0.38 for the array with 65 nm periodicity (i.e., for sample SU03 with 2R =45 nm). Similar RPTs, in other small magnetic particle systems driven by thickness, shape change, or microstructural effects were discussed in [4][5][6]. Actually, the problem of interacting wires, considered here, is quite similar to the one of superparamagnetic nanosphere arrays, described earlier [7,8].…”

Shape and strain-induced magnetization reorientation and magnetic anisotropy in thin film Ti/CoCrPt/Ti lines and rings

“…56,57 It is well known that patterning of a strained layer breaks the in-plane symmetry and produces an asymmetric strain relaxation, and changes the magnetoelastic anisotropy. There has been considerable work on patterned lines with perpendicular anisotropy, [10][11][12][13][14][15][58][59][60] but in most cases, the contributions of the magnetoelastic and surface anisotropy terms have not been considered. However, both terms have been shown to be important components of the net anisotropy, and in fact, they can dominate in certain cases such as patterned Cu/Ni/Cu stripes.…”

“…However, both terms have been shown to be important components of the net anisotropy, and in fact, they can dominate in certain cases such as patterned Cu/Ni/Cu stripes. [61][62][63][64] Domain size is also important, and both theoretical 60,65 and experimental 66 studies of nanolines with perpendicular anisotropy have shown that both the size and the orientation of the stripe domains depend on the lateral size of the wire.…”

Width-Dependent Transition of Magnetic Domain Configuration in Nanostructured CoFe/Pt Multilayered Nanowires

“…The formation of such distinct domain configurations is determined by the counterbalance between the magnetostatic and domain wall energies [9,10]. However, recently, it has been proposed that the geometry of magnetic nanostructures also modifies the domain configurations, resulting in a transition from the dendrite domain to the single domain with a decrease in the nanowire width [3,11]. Magnetic nanostructures with such a single-domain configuration are advantageous for use in domain-wall-mediated applications [1,2], because of the wall-motion-dominant domain dynamics in this configuration.…”

“…Recently, nanowires with perpendicular magnetic anisotropy (PMA) have attracted considerable interest owing to their unique advantages: smaller domain structures and superior stability [3]. PMA films exhibit three distinct domain configurations: single, dendrite, and scattered-dot domains [4][5][6][7][8], which are formed by domainwall motion, dendrite growth, and nucleation processes, respectively.…”
