Abstract / Description of output

We report the magnetic anisotropy of films of the magnetostrictive alloy galfenol deposited on a LiNbO3 substrate measured with the magneto-optic Kerr effect (MOKE). This anisotropy is present in 250 nm thick films but is absent in 600 nm thick films, most probably showing a loss in epitaxy with thickness. An anisotropy constant of = 3.45kJm−3 is deduced. Magnetic stripe domains (width 30 μm) oriented along the easy axis, parallel to the substrate () axis, could be created and imaged.
