MULTILAYER HYPERFINE MAGNETIC PARTICLE, AND METHOD AND DEVICE FOR FORMING MAGNETIC CONTINUUM USING THE MULTILAYER HYPERFINE MAGNETIC PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a method for forming multilayer hyperfine magnetic particles and a magnetic continuum using the multilayer hyperfine magnetic particles obtained by forming the magnetic continuum of the hyperfine magnetic particles on a substrate by forming, on a substrate, magnetic ink wherein multilayer hyperfine magnetic particles the surface of each of which is coated with low melting point alloy are dispersed so as to obtain an optional shape by using an ink jet drawing method, melting the low melting point alloy applied to the surface of each multilayer hyperfine magnetic particle of an optional shape stacked to form a multilayer, and subjecting the individual hyperfine magnetic particles to low temperature sintering or cold joining with each other, and to provide a method and a device for forming the multilayer hyperfine magnetic particles and a magnetic continuum.;SOLUTION: The hyperfine magnetic particles are obtained by adding, to one or more magnetic elements exhibiting ferromagnetism at room temperature, one or more metalloid elements and one or more additional metal elements for controlling the magnetic properties of the one or more magnetic elements. The surface of the hyperfine magnetic particles of a particle diameter of 1 to 500 nm are coated with a low melting point alloy.;COPYRIGHT: (C)2005,JPO&NCIPI
