Abstract
A novel method for determining magnetic anisotropies from hysteresis l oops is presented. While sweeping the loop, a magnetic field is applie d perpendicularly to the sweep-field axis. This causes the magnetizati on to rotate reversibly in a wide field range and still reach saturati on at finite fields. An example is given whereby surface and volume an isotropies are determined from magneto-optical Ken effect loops in Co films grown on stepped Cu(001). (C) 1997 American Institute of Physics .
