Observation of recoil magnetization curves outside the major loop in Co, Fe, and Ni films

We report a peculiar magnetization reversal observed in magnetron-sputtered Co, Fe, and Ni films. found that some recoil (minor) curves lie entirely way outside the major loop, phenomenon referred to here as recoil-curve overshoot. The greatly enhanced curve's remanence coercivity result an up 2.5-fold increase of loop's area. model pairs exchange-coupled grains with misaligned anisotropy axes reproduces, very good agreement experiment, all key features overshoot well kink loops present before saturation. disclosed ferromagnetic hysteresis provide further insights into this important classical phenomenon.
