Rare-earth zircons and intermetallic compounds in megagauss-fields: investigation of new magnetic phenomena

Abstract Magnetic phenomena of different material systems were studied in ultrahigh magnetic fields generated by the single-turn coil technique. We report on level crossing effects occurring in rare-earth zircons RXO 4 (R=rare-earth metal, X=P,V) and field-induced magnetic phase transitions in the rare-earth intermetallic compounds RMn 2 Ge 2 .
