Perturbed angular correlations investigations on YMnO3 multiferroic manganite

Abstract

The Perturbed Angular Correlation (PAC) technique was applied to study the yttrium local environment in YMnO 3 multiferroic manganite. The electric field gradients (EFG) at the Y site have been measured as function of temperature, covering both ferroelectric and magnetic transitions. The results were compared with point charge model (PCM) calculations.The experimental results show two different EFG distributions for all temperatures. Only one can be directly attributed to the yttrium crystalline site in the hexagonal structure.

Exploiting Radioactive Isotopes: from Pollutant Tracking to Solid State Studies Using a Combined Ab Initio and PAC Approach

“…We also studied one member of the rare‐earth hexagonal manganite family, YMnO 3 , with PAC measurements . The family of rare‐earth manganites with hexagonal structure displays ferroelectricity with high Curie temperatures T C ≈ 1000 K) which is advantageous for applications.…”

“…In the following manuscript we will make a review of the use of radioactive isotopes as local probes for solid state physics, and nanotechnology studies, with a particular emphasis on hyperfine interactions, where CICECO team has promoted and participated within the international collaboration at ISOLDE (Isotope mass Separator On‐Line facility) in CERN, a laboratory dedicated to the production of radioactive isotopes…”
