Abstract
The nuclear quadrupole resonance spectra of Eu3+ in YAlO3 single crystal at ∼ 10 K are reported. From the ratio of the quadrupole interaction parameters of 151Eu and 153Eu, the ratio of the quadrupole moments corrected for the pseudoquadrupole interaction is obtained Q153/Q151=2.5812±0.0010. With low-magnetic-field studies the anisotropic magnetic shielding factors are measured. They are αx=0.58, αy=0.80, αz=0.47 compared to an estimate of αz=0.89 by Elliott. A measured value ⟨r−3⟩=39 Å−3 is obtained using Elliott's formulation and the experimental values of the anisotropic magnetic shielding factors.
