Rare-earth magnetism is dominated by localized 4f electrons, relative to inner transition metals (that are mostly comprised of lanthanides) and cannot be directly excited through an optical laser pulse. As a result, ultrafast ...
Yoshihiro Iwasa and colleagues from the RIKEN Center for Emergent Matter Science, the University of Tokyo and Hiroshima University have discovered that ultrathin films of a semiconducting material have properties that form ...
