    Abstract

    Large scale 3D micromagnetic simulations are performed on single pole read heads with pole tip cross sections of 45345 and 1003200 nm. It is shown that tips with these dimensions have a much higher output than predicted by an analytical theory using the reciprocity theorem. The larger of these tips still behaves in a relatively soft manner and has an output waveform shape very close to the one predicted by the analytical model. The response of the small tip however is hysteretic.
