Lattice sites and collective ordering of highly oxygen doped samples of
HgBa2Can-1CunO2n+2+δ (n=2, 3, Hg-1212 and Hg-1223) were investigated
using the Perturbed Angular Correlation (PAC) technique by measuring the
electric field gradients at 199mHg nuclei. The experiments in these compounds
were performed at different annealing conditions, under Ar flow or O2 pressure
up to 152 bars....

At ISOLDE, CERN, an online test bench is dedicated to charge breeding
experiments with the Daresbury Phoenix booster ECR ion source. The
investigation of the 1+ --> n+ scenario for next generation ISOL post-
accelerators is ongoing for one more year, with charge breeding of stable and
radioactive elements. Many technical developments have been undertaken to
improve the flexibility of...

The valences of isolated Eu impurities at Pd surfaces and in ZnO semiconductor
crystals are intended to be determined from the oscillation patterns of the
perturbed angular correlation technique. After the production and the
implantation of appropiate precursor isotopes, the 11/2-isomeric levels in Eu-
149 and Eu-147 have been utilized. After annealing procedures, first successful...

The Mn3+/Mn4+ mixed valence manganite systems have very rich phase
diagrams [1] exhibiting charge, orbital, magnetic and dielectric competing
orders depending on doping, magnetic and electric applied fields, temperature
and pressure. The recent interest in multiferroic materials, displaying
coexistence of ferroelectricity and magnetic order has triggered further research
in...
