SUPERCONDUCTOR CAPABLE OF IMPROVING MAGNETIC PROPERTY THROUGH NON-MAGNETIC DISORDERS, A MANUFACTURING METHOD THEREOF, AND A MAGNETIC RESONANCE IMAGING APPARATUS THEREOF

摘要

PURPOSE: A superconductor, a manufacturing method thereof, and a magnetic resonance imaging apparatus thereof are provided to improve an upper critical magnetic field or critical current density by forming non-magnetic disorders and magnetic impurities in a superconductive material.;CONSTITUTION: Magnetism impurity impurities(11) and non-magnetic disorders(12) are formed inside super conductive materials. At least one among the critical magnetic field and critical current density of the super conductive materials includes magnetic impurities and does not include non-magnetic disorders. The super conductive materials comprise at least one selected from a group consisting of Nb_3Sn and MgB_2. The magnetic impurities actuates as the vortex pinning centers. The spin of the magnetic impurities are aligned to the ferromagnetism or the anti-ferromagnetism in the superconductor(10).;COPYRIGHT KIPO 2010
