摘要：

We demonstrate that pressure-induced magnetic phase transitions can be detected by optical second harmonic generation (SHG) measurements in diamond anvil cells and show that the transition from an acentric to a centrosymmetric magnetic structure occurs in Cr2O3 at 10(1) GPa. The pressure dependence of the Neel temperature, dT(N)/dP = -1.0(5) K/GPa from our SHG measurements, which differs significantly from earlier results where dT(N)/dP ranged from -16 K/GPa to +15 K/GPa.
