26. Development of large-area topological insulators for spintronics

Dr Roberto Mantovan (CNR-IMM Agrate Unit (IT))

Invited (In person)

Topological insulators (TIs) represent a state of matter in which the material bulk has insulating properties while the surface hosts highly conducting states [1]. In TIs, the presence of Dirac-like dispersed surface states jointly with the large spin–orbit coupling provides the so-called spin-momentum locking and generates topologically protected surface states [1]. Within this talk I will...

13. Application of PAC spectroscopy to metalloproteins

Lars Hemmingsen (University of Copenhagen (DK))

Submitted oral (online)

Time differential Perturbed Angular Correlation (PAC) of γ-rays spectroscopy may be applied to study the coordination geometry and dynamics at metal ion binding sites of proteins [1-2]. Selected examples relating to recent $^{199m}$Hg and $^{111}$Ag PAC experiments will be presented, such as 1) Ag(I) binding to human serum albumin - the major transport protein in blood; 2) A potential...

35. Structural formation yield of GeV centers from implanted Ge in diamond

Ulrich Wahl (Universidade de Lisboa (PT))

Submitted oral (online)

emphasized textGroup-IV vacancy centers in the so-called “split-vacancy configuration” in diamond are of high interest as spin-photon interfaces for a number of quantum applications, such as quantum information processing and quantum communication, with a particular focus on quantum networks [1-3]. However, the reliable and reproducible fabrication of germanium-vacancy centers has remained a...

43. A study of the local fields in bismuth ferrite by using different radioactive tracer ions

Thanh Thien Dang (Institut Fur Materialwissenschaft Universität Duisburg-Essen (DE))

Submitted oral (online)

This work presents the study of the local electric and magnetic fields in multiferroic bismuth ferrite (BiFeO3: BFO) using Time Differential Perturbed Angular Correlation (TDPAC) spectroscopy. The measurements were carried out at a wide range of temperatures up to 850oC, after the implantation of various radioactive tracer ions: 181Hf, 111In and 111mCd. The experimental results reflect the...

78. Local Probing Energy Efficient Perovskites

Armandina Maria Lima Lopes (Universidade do Porto (PT))

01/12/2023, 10:15

Invited (online)

Naturally layered perovskite phases such as the Ruddlesden-Popper present an inspiring route to achieve unique magneto-electric, ferroelectric–photovoltaic or negative thermal expansion effects, among others. In these structures, the rotations of the disconnected perovskite octahedra can lead to different symmetry groups, polar and non-polar, and different magnetic orders adding extra pathways...
