Zeeman Effect of the Purely Cubic Field Fluorescence Line of MgO:Cr3+Crystals

Abstract

Both transverse and longitudinal Zeeman effects are studied of the most conspicuous red emission line (14 319 ${\mathrm{cm}}^{-1\mathrm{}}$) of a MgO: ${\mathrm{Cr}}^{3+}$ single crystal. The Zeeman patterns are examined experimentally, with a magnetic field parallel to the [001], [110] and [111] axes, with linear polarizations parallel and perpendicular to each direction of the magnetic field and with circular polarizations around the magnetic field.
