Abstract
Exchange bias phenomena of nanocrystalline FeCuNbSiB ribbons have been investigated at room temperature. It was found that the rougher surface of ribbons annealed in longitudinal field played a main role in bringing the bias behavior in our ribbons. The topography of ribbon surfaces and the configuration of magnetic domains were specially observed in order to make clear the dependence of bias behavior on the induced magnetic anisotropy. A simple phenomenological explanation was also put forward to promote the comprehension of loop shift in ribbons and its possibility of potential applications. [ABSTRACT FROM AUTHOR]
