A nuclear orientation study of YbVO4
- 16 Downloads
Nuclear orientation studies on single crystals of tetragonal YbVO4 are reported, using the radioactive isotopes169Yb (I=7/2), and175Yb (I=7/2). The anisotropies for a number of gamma-rays of both isotopes have been measured at milliKelvin temperatures, in magnetic fields up to 0.6T applied along the c-axis. Striking variations of orientation are observed on ramping the magnetic field through the anticipated spin inversion phase transition, but only for those gammas emitted from and below the daughter169Tm 660ns level.
