Abstract :
An interwire magnetostatic coupling is one of the most important effects in the micro- and nanowire arrays, because of it strongly influences on the magnetization switching, spin-wave dynamics and magneto-transport properties. Manipulation of the magnetostatic coupling is possible not only by variation of a dimension of nanowires and geometry of arrays, but also by changing the magnetic anisotropy. In this paper, we report on an investigation of the magnetic behavior of arrays consisting of finite number of Co microstripes with two mutually perpendicular induced anisotropies. We have studied an effect of the interwire coupling on the switching field of magnetization and analyzed the domain structure of the arrays under an impact of the induced anisotropies.
