摘要：
The ground state of Gd3+ ions substituting for Y3+ in YAl3(BO3)(4) single crystal has been studied by EPR method. Spin Hamiltonian parameters and their signs for Gd3+ ion in trigonal symmetry (g(z) = 1.9893 +/- 0.0002, g(x) = g(y) = 1.9860 +/- 0.0002; b(2)(0) = 386.15 +/- 0.11; b(4)(0) = -12.65 +/- 0.07; b(6)(0) = 0.35 +/- 0.10) were determined. Structural phase transition manifested as a discontinuous change of splitting of spectrum was observed near 157 K. (C) 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
