Vector form of wipe-out memory and its experimental testing

It was recently suggested that, when magnetic field varies arbitrarily in b oth direction and magnitude, certain portions of the magnetic field traject ory can be replaced without any effect on the resulting magnetization and i ts subsequent evolution. Here, this vector form of wipe-out memory is teste d experimentally for particulate iron oxide magnetic medium using a vibrati ng sample magnetometer by generating magnetic field trajectories that are s elf-crossing. It is shown that for the class of the trajectories considered here the suggested vector form of wipe-out memory is agrees well with expe rimental data.
