cited By (since 1996)0International audienceIn this paper we consider a one-dimensional model of ferromagnetic nanowire subject to a nonconstant electromagnetic field. Taking into account the ratio between the exchange length and the length of the wire, we prove that the wall configurations are persistent in a large time interval. © 2014 Society for Industrial and Applied Mathematics
