Magnetic modelling of GMR hysteresis and applications of the modelling

In the past several years, there has been some interest in modelling hysteresis in giant magnetoresistance (GMR) as a function of magnetic field in magnetic multilayer films. The purpose of this paper is to review work published a decade ago on such modelling and on application of such modelling to the design of a GMR field sensor. The computed GMR curves qualitatively reproduce the GMR hysteresis seen experimentally. In particular, two GMR peaks are found to be symmetrically placed about
