摘要：

The Zeeman effect has been studied within the "green" range of luminescence due to the radiative 4f -> 4f transitions (5)D(4)->(7)F(5) for the rare earth ion Tb(3+) in yttrium aluminum garnet (Y(3)Al(5)O(12)) at a sample temperature of 85 K. The special features associated with the magnetic field dependence of the Zeeman splitting have been explained for transitions observed in the geometry of the longitudinal and transverse Zeeman effect. An analysis of the results obtained from the magneto-optical data indicates that in a magnetic field a nonequilibrium population distribution occurs between the sublevels of the quasidoublet state (Gamma(1),Gamma(4)) in the (5)D(4) manifold. The energy of the quasidoublet state is approximately 20 585 cm(-1). (C) 2008 American Institute of Physics.
