ZnO DMS were prepared by co-precipitation method. Single phase Zn0.90Co0.05Ni0.05O was confirmed by powder X-ray diffraction (XRD). The samples were characterized by EDS to confirm the expected stoichiometry. SEM revealed no surface precipitation of

Radiation-induced defects are studied in cubic rhodium metal, using the local probe technique ‘Time differential perturbed angular correlation’ (TDPAC) at liquid N2 temperature. Isochronal annealing was done at 300, 1073 and 1473 K temperatures.

Hyperfine interaction techniques like Mossbauer spectroscopy are very sensitive tools to study the local probe interactions in dilute magnetic semiconductors. We report here a Mossbauer study on the concentration dependence in Fe0.008Ge1−x Tex for

TDPAC study of InBi1−x Te x with x=0.0, 0.01, 0.05, 0.1 and 0.2 as a function of temperature is done. Both pure and Te-doped samples show a semi-metallic character up to around room temperature. Above room temperature a steep transition to semicond

Mossbauer study of semimetals is of great importance in understanding the origin of hyperfine interactions in these materials. A concentration dependence study in FexSb1−x for x=0.0025, 0.005, 0.01, 0.05, 0.10 and 0.20 is reported. It was found tha

Probe-impurity interactions of In–Cd and In–Zn pairs in silver matrix have been studied using 111In-TDPAC measurements. The interactions are repulsive for both the pairs. For 3% alloys, the interaction energy of In–Cd pairs in Ag is 51± 2 meV

The EFG in IV–VI compound semiconductor SnSe was studied using two hyperfine interaction techniques, namely, TDPAC and Mossbauer spectroscopy. The EFG in this material increases sharply up to 300 K and thereafter at higher temperatures it gets satu

BaHfO3 is prepared by sintering a mixture of BaCO3 and HfO2 giving the same heat treatments as for YBa2Cu3O7−δ (YBCO). X-ray diffraction analysis confirms the formation of cubic BaHfO3 along with some unreacted HfO2. A181Ta TDPAC study of the samp
