Dual substitution induces room-temperature ferromagnetism and negative thermal expansion in BiFeO₃
Using a dual-cation substitution approach, researchers at Science Tokyo introduced ferromagnetism into bismuth ferrite, a well-known and promising multiferroic material for next-generation memory ...
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 ...
