Micromagnetics of submicron (110) Fe elements

Micromagnetics of submicron „110... Fe elements

The magnetization processes and the domain structure of epitaxial ~110! Fe submicron-sized elements are studied experimentally and with micromagnetic simulations. Magnetic force microscopy and Kerr magnetometry results are in good agreement with the simulations, thus allowing the development of a consistent picture of the micromagnetics of these systems. © 2000 American Institute of Physics. @S...

Micromagnetics of mesoscopic epitaxial „110... Fe elements with nanoshaped ends

The magnetization reversal and magnetic domain configurations of 0.5-mm-wide epitaxial ~110! Fe particles with rectangular and needle-shaped ends and competing magnetic anisotropies have been investigated. Magnetic force microscopy imaging and longitudinal Kerr hysteresis loop measurements in conjunction with micromagnetic simulations have been used to elucidate the basic micromagnetic behavior...

Growth and morphology of the epitaxial Fe(110)/MgO(111)/Fe(110) Trilayers

Growth and surface morphology of epitaxial Fe(110)/MgO(111)/Fe(110) trilayers constituting a magnetic tunnel junction were investigated by low-energy electron diffraction (LEED) and scanning tunneling microscopy (STM). STM reveals a grain-like growth mode of MgO on Fe(110) resulting in dense MgO(111) films at room temperature as well as at 250 C. As observed by STM, initial deposition of MgO le...

Micromagnetism and magnetization reversal of micron-scale „110... Fe thin-film magnetic elements

Magnetic force microscope ~MFM! imaging in conjunction with longitudinal Kerr hysteresis loop measurements have been used to investigate the micromagnetic behavior of micron scale epitaxial ~110! bcc Fe thin-film elements ~50-nm thick! with rectangular, triangular, and needle-shaped ends and competing magnetic anisotropies. Thin-film elements of 2-mm width and 6-mm length and greater have been ...
