Abstract :
We report on magnetoresistance measurements in thin nickel films modulated by a periodic magnetic field emanating from micromagnetic arrays fabricated at the film surface. By increasing the strength of the magnetic potential using nickel and dysprosium micromagnets, we are able to quench the anisotropic magnetoresistance (AMR). We also observe mesoscopic magnetoresistance fluctuations, which possibly are related to the magnetic potential and size effects.
