Abstract
Provided is an iron-based superconducting material including an iron-based superconductor having a crystal structure of ThCr2Si2, and nanoparticles which are expressed by BaXO3 (X represents one, two, or more kinds of elements selected from a group consisting of Zr, Sn, Hf, and Ti) and have a particle size of 30 nm or less. The nanoparticles are dispersed in a volume density of 1×1021m−3 or more.
