抄録

Magneto-luminescence of R-lines has been studied in alexandrite subjected to quasi-hydrostatic pressures near 8 GPa at 77 K. In contrast to the previous experiment under lower pressures, the Zeeman spectrum exhibits Paschen-Back behavior if a magnetic field up to 15 T is applied parallel to the b- and c-axes of the crystal. This phenomenon reflects that the transverse moment of spins of the ²E term of Cr³⁺ ions is significantly reduced by pressure. Pressure strengthens the Ising character of the spins by elevating axial symmetry of the crystal field.
