Invited talk

Ferromagnetic Shape Memory Alloys (FSMAs) are a group of active materials that undergo martensitic transformations induced by temperature, stress and/or magnetic fields, which result in large recoverable mechanical deformations. Their fast response and high energy density makes them ideal candidates for implementation in sensors and actuators. The magnetic properties of FSMAs depend on the...

Contributed talk

RuO$_2$ initially attracted interest in the field of catalysts and microelectronics, but the recent report of antiferromagnetic order occurring above room temperature and its identification
as an altermagnetic state boosted activities on this material [1,2,3].
The combination of spin splitting otherwise characteristic for ferromagnetic order with the linear magnon dispersion of an...

Contributed talk

Mn$_3$Sn is one of the first antiferromagnetic compounds to exhibit an anomalous hall effect. Mn$_3$Sn is a frustrated Kagome metal with a broken time reversal symmetry leading to a non-zero Berry curvature, which in turn leads to a large and controllable anomalous Hall effect.

Depending on the exact stoichiometry of the sample, two main types of Mn$_3$Sn occur. One type exhibits a...

Poster

Semiconductors with composition A1−xBxC find widespread applications in solid-state devices due to their tunable bandgap. Cd0.9Zn0.1Te is a very attractive ternary semiconductor material for x-ray and gamma-ray detectors. Single-crystal diffuse scattering provides very detailed information about the local structure. We have measured diffuse scattering in a single crystal of Cd0.9Zn0.1Te using...

Poster

Motivation

The tetragonal distortion in spinel structures, such as CuFe$_2$O$_4$, CuCr$_2$O$_4$, and NiCr$_2$O$_4$, has garnered significant attention due to its profound influence on structural and magnetic properties [1]. Among these, CuFe$_2$O$_4$ is unique as it is ferromagnetic at room temperature. The tetragonal distortion in CuFe$_2$O$_4$ has been explained using semicovalent...
