71. Structure-property correlation from quantum crystallography perspective

Anna Malgorzata Krawczuk (Georg-August-Universitaet Gottingen (DE))

Invited (online)

Understanding the structure-property correlation in molecular materials is crucial for predicting the mechanical, electrical and optical properties of bulk materials. Our primary goal is to elucidate how molecules self-assemble in the crystalline state and to identify which intermolecular interactions determine specific physical properties. Among many possibilities, quantum crystallography...

74. Particle boundary in agglomerate enhances ferromagnetism in bismuth ferrite nanoparticles

Prof. Doru Constantin Lupascu (Institute for Materials Science and Center for Nanointegration Duisburg-Essen (CENIDE), University of Duisburg-Essen, 45141 Essen, Germany)

Invited (In person)

The nature of ferromagnetism in multiferroic bismuth ferrite (BiFeO3 or BFO) nanoparticles is still the subject of intense debate. The Time Differential Perturbed Angular Correlation (TDPAC) technique monitors local fields at the atomic scale without altering the structure of the materials under investigation. Using such an approach, we investigate that BFO nanoparticles exhibit strong...

8. Local effects in vanadia-based compounds

The current study focuses on the temperature-dependent structural modulation of the local environment of M2+ ions in vanadium bronzes MxV2O5 and vanadates xMnO-V2O5. The growing interest in V2O5-based materials is in view of their potential for cathodes in M ion batteries, as highlighted in recent research [1]. Although the (de)intercalation mechanism of M ions is considered fundamental to...

39. PACIFIC2: a cost-effective solution for digital data acquisition and processing in PAC spectroscopy

Pedro Miguel Da Rocha Rodrigues (Universidade do Porto (PT))

28/11/2024, 12:30

Submitted oral (In person)

The γ-γ Perturbed Angular Correlation (PAC) spectroscopy's unique ability to probe atomic-scale phenomena makes it an exciting technique for studying structural, magnetic, and orbital phase transitions in solid-state physics, as well as investigating the intrinsic properties of radioactive nuclei. [1-3]
Historically, ISOLDE's PAC setups relied on aging analog equipment, some over 30 years...
