Magnetization Reversal by Rotation in Magnetic Thin Films Deposited on Step Bunched Si(111) Substrates
Magnetic and magnetoresistive properties of magnetic thin films deposited on periodically structured substrates have been studied. By using a thermodynamical heat treatment, we activate the step bunching pheno...

Structural and Magnetic Study of Fe Stripes and Boxes Patterned by the <Atomic Saw>Method
The <Atomic Saw> method has been successfully used to cut a Fe thin film, epitaxially grown onto a (001) MgO substrate, into stripes (widths ranging from 1 μm to 100 nm) and boxes (lateral sizes ranging from 1...

Nanotesla Detection Using the Planar Hall Effect
A magnetic field sensor based on the planar Hall effect has been developed using epitaxial permalloy (Ni80Fe20) ultrathin films (1-10 nm). The magnetic and magnetotransport properties of these films have been stu...

Giant Magnetoresistance of (001) Fe / (001) Cr Superlattices
We recently reported the observation of a very large magnetoresistance in (001)Fe/(001)Cr superlattices grown by MBE. The magnetoresistance is found to be very large for thin Cr layers. We ascribe this magneto...
