Abstract
A thin film magnetic device includes an organic insulating layer of a raised shape and a soft magnetic alloy thin film covering the organic insulating layer. The soft magnetic alloy thin film has a composition which varies to provide a magneto-striction distribution such that magnetostriction is positive or negative in a top region and negative or positive in a bottom region of the raised shape whereby the device has uniaxial anisotropy in a desired direction.
