Ballistic 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 کاملZeeman splitting in ballistic hole quantum wires.
We have studied the Zeeman splitting in ballistic hole quantum wires formed in a (311)A quantum well by surface gate confinement. Transport measurements clearly show lifting of the spin degeneracy and crossings of the subbands when an in-plane magnetic field B is applied parallel to the wire. When B is oriented perpendicular to the wire, no spin splitting is discernible up to B = 8.8 T. The obs...
متن کاملBallistic electron magnetic microscopy studies of magnetization reversal in CoÕCuÕCo trilayer films
We have used ballistic electron magnetic microscopy to image, with nanometer resolution, the magnetization behavior of Co/Cu/Co trilayer films in the presence of a magnetic field. Films prepared both by thermal evaporation and by magnetron sputtering have been studied. In each case we have observed both large, ;500 nm, domain structures, and much smaller, apparently randomly dispersed, regions ...
متن کاملObservation of magnetization reversal of thin-film permalloy nanostructures using ballistic electron magnetic microscopy
We have imaged the magnetization reversal process of thin-film permalloy (Ni80Fe20) nanostructures using ballistic electron magnetic microscopy. Their switching behavior is often influenced by the formation of end domains and the subsequent domain-wall propagation under application of a magnetic field. Occasionally, this process leads to the formation of a 360° domain wall that is stable in fie...
متن کاملBallistic electron microscopy study of ultrathin oxidized aluminum barriers for magnetic tunnel junctions
Ballistic electron emission microscopy has been used to study thin aluminum oxide tunnel junction barriers formed both by magnetron sputter deposition and thermal evaporation. We have found that the barriers made by oxidation of evaporated Al become fully formed at a significantly thinner mean deposited thickness ~;6 Å! than junctions made by sputter deposition. The effective barrier height of ...
