Abstract
PURPOSE:To realize a magnetic material at a liquid nitrogen temperature or above so that it has complete diamagnetism and ferromagnetism by the use of a magnetic field, a current, and light, by forming ferromagnetic materials into a superconductor. CONSTITUTION:Needlelike ferromagnetic materials 2 made of needlelike CuFe2O4 are mixed into powder of a Y-Ba-Cu-O superconductor 1. This mixed material is put into a copper pipe 3 and this pipe is extended to be shaped cylindrically. When the pipe is cooled at 77K by liquid nitrogen and a magnetic field is applied longitudinally to the pipe to measure magnetism, it shows ferromagnetism rapidly at the time of HC1. When the pipe is heated at 500 deg.C and next it is measured again at 77K, it shows diamagnetism. When a magnetic field of HC1 or below is applied to the pipe and its magnetism is measured together with the flowing of the current, JC1 shows ferromagnetism rapidly.
