Altermagnetism from a strong-coupling perspective

14:00

Hall D and Zoom platform, Insitute of Physics P.A.S.

Recently, a new form of magnetism has been proposed -- so-called altermagnetism. While altermagnetism has mostly been discussed within the itinerant picture, here I would like to provide a brief overview of three important aspects related to altermagnetism in the strong-coupling limit. First, I will discuss why one of the most prominent examples of strong-coupling altermagnetism is difficult to observe in real materials [1]. Next, I will explore whether there is a way to observe altermagnetism in strongly correlated copper oxides [2]. Last but not least, I will examine an interesting scenario for detecting altermagnetism in the strongly correlated limit using ARPES [3]. [1] V. Leeb, A. Mook, L. Šmejkal, and J. Knolle; Phys. Rev.

Physical properties of emerging two dimensional van der Waals quantum materials

14:00

Institute of Physics P.A.S.

In recent years two-dimensional van der Waals materials are at the forefront of research in condensed matter physics and material science. On the one hand the magic angle bi-layer graphene has set a new trend in unconventional superconductivity. On the other hand the presence of long range magnetic order in two-dimensional van der Waals materials has completely opened a new avenue for the investigation of magnetism in true 2D-systems. In my talk I will present explorative research of these emerging two dimensional quantum materials. Highlighting the aspects of the intimate relation between long range magnetic order, topology and superconductivity in these systems. Later, I will discuss detailed anisotropic magnetic properties aiming to understand the ground states of selected compounds. Ref: 1. Phys. Rev. Materials, 5, 073401, (2021) 2. Electron.

High-frequency susceptibility with inertia and nutation resonance in ferromagnets: opportunities for sub-THz magnonics
Cancelled

14:00

Institute of Physics P.A.S., Warszawa

The onset of additional high-frequency resonance in ferromagnets due to inertia of magnetization has been shown first theoretically [1] and then experimentally [2,3]. The existence of sub-THz resonant frequency in ferromagnetic materials and ability to excite the magnetization nutation coupled to its precession significantly broadens the potential range of applications of ferromagnets in ultrafast magnetism. While several theoretical studies have been mostly addressing the dependence of the nutation resonance frequency on the inertial relaxation time [4,5], the understanding of the influence of the materials parameters on the overall magnetic susceptibility behavior including the precession and nutation magnetic resonances is still missing. We present an analytical study of the linearized high-frequency susceptibility tensor using the Polder-Ansatz for the ferromagnetic systems exhibiting the inertia of magnetization and resolve the effect of Gilbert damping constant and inertial time as
