Abstract

The magnetic hyperfine fieldH hf and the electric field gradientV zz at181Ta impurties in metallic Gd were determined by time differential perturbed angular correlation measurements with the 133 keV K-conversion electron 482 keV γ-cascade of181Ta. The sources for these measurements were prepared by implantation of radioactive181Hf ions into Gd. The results are: |H hf(TaGd; 77 K)|=285(14)kG, and |V zz(TaGd; 330 K)|=5.32(15)·1017V/cm2. The value ofH hf fits well into the systematics for 5d impurities in Gd and indicates a positive core polarisation contribution, which is expected if the conduction electrons of Gd have to a large extent d-character. The electric field gradients of the 5d impurities in Gd are not consistent with a proportionality between the ionic and the electronic contribution.
