Anisotropic transport behavior in ultrathin epitaxial Fe films on vicinal oxide substrates
SHVETS, IGOR; MCEVOY, CIARAN (2005)Step-induced anisotropy of electron transport in ultrathin Fe film was investigated. The Fe films (2 and 10 nm) were deposited on vicinal MgO (100) substrate using molecular-beam epitaxy. It is found that the films with a ... -
The magnetic and magnetoresistance properties of ultrathin magnetite films grown on MgO substrate
SHVETS, IGOR; MCEVOY, CIARAN; RAMOS, RAFAEL (AMERICAN INSTITUTE OF PHYSICS, 2006)We report on the properties of ultrathin (2, 4, 6, and 8?nm) epitaxial films of magnetite, Fe3O4, grown on MgO (100). Atomic force microscopy image and V-I curves suggest that the films at this thickness are still continuous. ... -
Proximity influence of a ferromagnet on the magnetoresistance of Cr film across a nonmagnetic layer
SHVETS, IGOR; MCEVOY, CIARAN (2004)(5 nm) Cr (100)/( x nm) MgO (100)/(30 nm) Fe3O4 (100) (1 < x < 6 nm), as well as (5 nm) Cr (100)/(5 nm) MgO (10 0) structures were grown on MgO (10 0) substrates using molecular beam epitaxy. The proximity influence of the ...
