Abstract
Ferrite disk cores and laminated disk cores composed of Ferrite and Permalloy films were prepared by Spark-Plasma-Sintering (SPS) method. Soft magnetic ferrite disk core with small number of void was obtained when SPS was carried out for long time. Ferrite/Permalloy laminated disk core prepared by SPS shows high bonding strength, high saturation magnetic flux density and superior soft magnetic properties at high frequencies. This laminated disk core is one of the promising candidates for high performance new magnetic core used in inductors, transformers and magnetic heads of card reader.
