Dual cation substitution method for engineering magnetism and thermal expansion in bismuth ferrite (BiFeO3)

Caption

Researchers simultaneously substituted calcium at the bismuth site and ruthenium or iridium at the iron site to suppress the cycloidal spin structure, enabling room-temperature weak ferromagnetism and enhancing magnetic stability and negative thermal expansion.
