Abstract
PURPOSE:To improve the efficiency of using a magnetic memory which uses a superconductor by effectively stabilizing lines of magnetic induction and splitting sectors of the above-mentioned memory. CONSTITUTION:The magnetic memory recording medium consisting of the superconductor is constituted of memory regions 3 contg. 10<15-17> pieces/cm<3> different elements and the boundaries 2 of the memory sectors contg. 10<18-20> pieces/cm<3> different elements. The term 'different elements' refers to the elements except R, X, Z, D which are the compsn. of the superconductor. R of the compsn. of the superconductor is Sc, Y, La and elements of lanthanoid groups; X is the elements of group II of the periodic table and is more preferably Ba, Sr, Ca; Z is transition metal elements and is more preferably Cu; D is group VI chalcogen elements of the periodic table and is more preferably O. The compd., of which R is Y, X is Ba, Z is Cu, D is O, and r is 1.0, x is 1.4-2.1, z is 2.4-3.2, 9.0>delta>5.0, when the superconductor is expressed by the formula RrXxZzDdelta, is suitable.
