Abstract

A method of flux conduction comprising providing a structure with anisotropy not purely in the transverse in-plane direction such that flux spreading into the transverse in-plane direction can occur by rotation. This method of flux conduction is used in magnetic devices having coupled magnetic layers or coupled magnetic domains. Devices disclosed which utilize this method can function as a magnetic recording head, bubble memory, magnetic field structure, magnetic field sensor, transformer, laminated magnetic memory element or magnetic shield.
