Magnetic energy and domains
(5) Two things are worth to notice. First, the energy only involves an integration over the space occupied by the sample (where M is non-zero). Second, the applied field H0 is the independent variable in the final expression. This is in accordance with the experimental situation and is in contrast with the original expression (4), which involves B as the independent variable. The magnetic energ...
متن کاملMagnetic domains in III-V magnetic semiconductors
Recent progress in the theoretical understanding of magnetic anisotropy and stiffness in III-V magnetic semiconductors is exploited for predictions of magnetic domain characteristics and methods of their tuning. We evaluate the width and the energy of domain walls as well as the period of stripe domains in perpendicular films. The computed stripe width W51.1 mm for Ga0.957Mn0.043As/In0.16Ga0.84...
متن کاملBallistic electron magnetic microscopy: Imaging magnetic domains with nanometer resolution
A variation of ballistic electron emission microscopy has been developed to image magnetic structure in thin-film multilayers with nanometer resolution. In studies of nominally uncoupled Co/Cu/Co trilayer films, magnetic domains and domain-wall motion are readily observable with this technique. In the Co/Cu/Co trilayer system magnetic domains are found to occur on an ;500-nm-length scale and le...
متن کاملDistinction of magnetic non-ferroelastic domains.
It is shown that there always exists a coordinate system in which components of property tensors that distinguish between the domains of a magnetic non-ferroelastic domain pair differ solely in the two domains by a change in sign. The 309 classes of twin laws of magnetic non-ferroelastic domain pairs are listed and the twin laws, which are given in a coordinate system where the tensor distincti...
متن کاملBirdsong dialect patterns explained using magnetic domains.
The songs and calls of many bird species, like human speech, form distinct regional dialects. We suggest that the process of dialect formation is analogous to the physical process of magnetic domain formation. We take the coastal breeding grounds of the Puget Sound white crowned sparrow as an example. Previous field studies suggest that birds of this species learn multiple songs early in life, ...
