Title:
FERROUS COMPOUND, SUPERCONDUCTION WIRE, AND METHOD FOR PRODUCING FERROUS COMPOUND
Document Type and Number:
Japanese Patent JP2019049030
Kind Code:
A
Abstract:
To provide a ferrous compound that can reduce variations in superconducting transition temperature T.SOLUTION: In a ferrous compound (10) represented by chemical formula AA'FeAs, A is La and Na, and the A' is at least one element selected from Rb and Cs. The ferrous compound (10) has a crystal structure in which AFeAslayers (16) and A'FeAslayers (17) are alternately laminated, and the space group of the crystal structure is a simple tetragon of P4/mmm.SELECTED DRAWING: Figure 1
