Temperature dependence of 27Al NMR in YAlO3
Abstract
The nuclear quadrupole tensor for 27Al in yttrium ortho-aluminate has been measured between 30°C and -150°C. The coupling constant e2qQ h varies linearly from 1.44 to 1.56 MHz over this range, whereas the asymmetry parameter η drops rapidly from 0.748 toward an asymptotic value of 0.663. © 1982.
