Moving sector walls on the nano scale
Zurich, Switzerland (SPX) Jun 16, 2015
Most magnetic materials have a structure that is somewhat more complicated than a commercially available domestic magnet: they not only have a north and south pole, but a variety of sectors, often only a few nanometres in size, in each of which the magnetic axis points in a different direction. These sectors are referred to as domains. Over the past few years, Manfred Fiebig, Professor for Multifunctional Ferroics at ETH Zurich, has been studying the walls between adjoining domains in certain mate ... read more
