Abstract
Ternary rare-earth intermetallic Laves phase compounds Tb0.1Dy0.9Fe2, grown by MBE, were characterized by a vibrating sample magnetometer (VSM) and magneto-optical Kerr effect magnetometry (MOKE). Striped arrays with 5 μm-width along an in-plane easy-axis [â1,1,0] direction were defined by a UV direct write system in 400 nm-thick (1 1 0) epitaxial Tb0.1Dy0.9Fe2 films. An additional shape anisotropy of 2.7 Ã 105 erg/cm3 in magnitude is induced. MOKE measurements reveal pronounced enhancement of the switching field along [â1,1,0] direction. However, the switching field along the hard-axis [0 0 1] direction is unchanged as the intrinsic anisotropy along the [0 0 1] direction is an order of magnitude larger than the induced one. The results demonstrate a possibility of engineering the magnetostriction-to-anisotropy ratio by patterning in epitaxial TbDyFe2 magnetostrictive materials.
