METALLIC NANOPARTICLE CLUSTER, ITS MANUFACTURING METHOD, ITS TREATMENT METHOD AND RECORDING MEDIUM USING AT LEAST MAGNETISM

摘要

PROBLEM TO BE SOLVED: To to form a magnetic film composed of fine, uniform magnetic particles and to reduce noise by suppressing the irregular agglomeration of magnetic metal nanoparticles with respect to a metallic nanoparticle cluster, its manufacturing method, its treatment method and a recording medium using at least magnetism.;SOLUTION: The metallic nanoparticle cluster 3 is constituted in such a way that it forms a structure composed of an agglomerate of metallic nanoparticles 1 of 0.5 to 10 nm diameter and the diameter of the cluster as an agglomerate does not exceed 100 nm.;COPYRIGHT: (C)2004,JPO
