Ballistic electron magnetic microscopy: Imaging magnetic domains with nanometer resolution
نویسندگان
چکیده
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 less, while smaller-scale fluctuations in the ballistic electron transport properties of the system are found on an ;10 nm length scale. © 1999 American Institute of Physics. @S0003-6951~99!03933-9#

Ballistic 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 کاملGrowth of Magnetic Tunnel Junctions
Three applications of ballistic electron microscopy are used to study, with nanometer-scale resolution, the magnetic and electronic properties of magnetic multilayer thin films and tunnel junctions. First, the capabilities of ballistic electron magnetic microscopy are demonstrated through an investigation of the switching behavior of continuous Ni80Fe20 /Cu/Co trilayer films in the presence of ...
متن کاملAtomic Force Microscopy of Chromatin
Atomic force microscopy or scanning tunneling microscopy (AFM/STM) is a powerful single molecule tool for the visualization of biological materials at sub-nanometer resolution. AFM is versatile because it can directly measure physical properties due to its sensitivity at picoNewton force scales, thus enabling dissection of molecular forces. STM/AFM has been considered revolutionary since its di...
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 کاملSparse reconstruction of molecular images: the MRFM challenge
Recently, an emerging technology called magnetic resonance force microscopy (MRFM) has demonstrated the ability to detect and localize magnetic force signals originating from individual electron spins and from small ensembles of nuclear spins. By measuring weak magnetic forces from hydrogen nuclei, three dimensional (3D) magnetic resonance images with nanometer resolution have been successfully...
