Abstract

The quantitative characterization of the magnetic force microscopy (MFM) probe tip magnetization tilt in point-dipole approximation is carried out to prepare calibration samples for measurements in external in-plane magnetic fields. The results showed that the tilt of the probe tip magnetic dipole moment [thetas] that strongly depend on the magnetic history could be used to separate the influence of the tip's magnetization tilt from the sample magnetization in further MFM measurements.

Abstract

Exchange-biased IrMn/CoFe full films are magnetically structured with He-ion bombardment into stripes with antiparallel-aligned loop shift. The results indicate that the longitudinal magnetization reversal through head-on domain-wall motion and partial penetration of magnetization from neighboring strips is highly asymmetric.
