Nuclear Magnetic Resonance Studies ofEu151andEu153in Europium I

Abstract

The nuclear magnetic resonances of Eu 151 and Eu 153 have been studied in single crystals of europium iron garnet with externally applied fields of sufficient magnitude to align the magnetization along various crystallographic directions. Hyper fine-field and quadrupole-splitting parameters are obtained. Contributions to the electric field gradients and anisotropic hyperfine fields are discussed and compared with theory.
