“…The time resolution of the system was about 0.6 ns for the 140 Ce gamma cascade. A detailed description of the method can be found elsewhere [2,3]. The experimental data for temperatures below T N were analyzed for a pure magnetic dipole interaction.…”

Perturbed gammaYgamma angular correlation technique was used to measure the magnetic hyperfine field at Gd sites in the intermetallic compound GdAg using the 140 LaY 140 Ce nuclear probe. A major and well-defined magnetic interaction is observed at 140 Ce substituting Gd sites in GdAg below 130 K, corresponding to a ferromagnetic ordering of Gd moments. The temperature dependence of magnetic hyperfine field, however, shows a sharp deviation from an expected Brillouin-like behavior for temperatures below 75 K. This additional magnetic interaction is believed to result from the polarization of Ce spin moments induced by the magnetic field from Gd atoms.

“…In order to check reliability of the presented results, we calculated the electric field gradient (EFG) at the Cd impurities in both delafossites, and compared them with the experimental data [8]. Very good agreement between these values (Table 1) indicates that the presented calculations succeeded to describe the ground state of the impurity-containing systems correctly.…”

We performed the first-principles band-structure calculations for a pure and a Cd-doped AgInO 2 delafossite compound. The results are carefully analyzed and compared with the results obtained for a pure and a Cddoped CuAlO 2 compound, calculated previously by our group. The electronic structures of both systems are found to be similar in many details, being characterized by the same hybridization scheme that occurs at both Cu and Ag positions. Introduction of Cd impurity into the Cu site produces a shallow band within the CuAlO 2 gap, while the Cd presence at the Ag site creates a wide band pinned at the Fermi level in the AgInO 2 spectrum. In both cases, however, the n-type conductivities are predicted.

Perturbed Angular Correlation method has been used to study the hyperfine magnetic field in the Heusler alloy Pd 2 MnSb(Sn). Ion implantation of the recoil 111 In nuclei following heavy ion nuclear reactions 108 Pd( 7 Li, 4n) 111 In and 108 Pd( 6 Li, 3n) 111 In has been used to great advantage in the present case resulting in large implantation efficiency. Only a few hours of irradiation time with moderate beam current of the order of 400Y500 nA resulted in sufficient implanted 111 In activity on the sample for good quality measurements. The hyperfine field was measured at 111 Cd probe nuclei substituting Mn and Sb(Sn) sites as a function of temperature. The fraction of 111 Cd nuclei occupying Mn atom sites was found to increases with the annealing of sample at higher temperatures.
