Abstract

The paramagnetic relaxation of Er in an Er single crystal was measured at T≫T_N and compared to the relaxation of Er ions in a polycrystalline Pb host. The results indicate an enhancement of at most 50% of the f-conduction electron exchange interaction in Er, as expected for highly ionic f-orbitals. The ratio of the quadrupole moments of the¹⁵⁴Er(I^π=11^-) and the¹⁵⁵Er(I^π=13/2⁺) isomers was measured to be 1.18(3) indicating onset of nuclear deformation at N=87.
