Abstract
We investigate how the choice of the magnetization distribution inside a sample affects its interaction with an external electromagnetic hel d. Strong selectivity to the time-dependence of the external electroma gnetic field arising for particular magnetizations suggests that it ca n be used for storage and ciphering of information. We propose a time- dependent Aharonov-Bohm like experiment in which the time-dependence o f the interference picture is due to the time variation of the magneti c flux confined to the excluded region. The arising time-dependent int erference picture may be viewed as a new channel for information trans fer. Examples are given of current configurations generating static el ectric fields adequately described by an electric vector potential rat her than by a scalar one.
