Abstract

The electric and (antiferro-)magnetic hyperfine interaction of111Cd in α-Cr2O3 after111In implantation was studied via PAC. Two fractions with axially symmetric electric field gradients were observed having antishielding factors of Vzz/Vzz pc=79(12) and 106(16), respectively. From the line broadening of the Fourier components of the first fraction its supertransferred magnetic field was estimated as Bloc (20 K)≤0.41 T, about two orders of magnitude smaller than for substitutional111Cd in NiO and CoO.
