“…10 Subsequently, theoretical calculations on CrO 2 have predicted abundant structural phase transitions under higher pressure. 11,12,[18][19][20][21] Notably, most structural phase transitions are accompanied by changes in electrical or magnetic properties, such as from FM to paramagnetic, 22,23 HM to metal, 22,24 FM to nonmagnetic to FM insulator, 11 FM to half-semiconducting, 18 maintaining HM and FM to 95 GPa, 25 etc. High pressure and high-temperature conditions were employed by Wang et al to explore their influence on the magnetic and transport properties of CrO 2 after cooling and releasing pressure.…”
