Magnetism in AV3Sb5 (A = Cs, Rb, K): Complex Landscape of the Dynamical Magnetic Textures
Debjani Karmakar, Manuel Pereiro, Md. Nur Hasan +10
We have investigated the dynamical magnetic properties of the V-based kagome stibnite compounds by combining the ab-initio calculated magnetic parameters of a spin Hamiltonian like…
Magnetism in AV3Sb5 (Cs, Rb, K): Origin and Consequences for the Strongly Correlated Phases
Md. Nur Hasan, Ritadip Bharati, Johan Hellsvik +10
The V-based kagome systems AV3Sb5 (A = Cs, Rb and K) are unique by virtue of the intricate interplay of non-trivial electronic structure, topology and intriguing fermiology, render…
Ultrafast Demagnetization through Femtosecond Generation of Non-thermal Magnons
Markus Weißenhofer, Peter M. Oppeneer
Ultrafast laser excitation of ferromagnetic metals gives rise to correlated, highly non-equilibrium dynamics of electrons, spins and lattice, which are, however, poorly described b…
First-principles calculation of orbital Hall effect by Wannier interpolation: Role of orbital dependence of the anomalous position
Dongwook Go, Hyun-Woo Lee, Peter M. Oppeneer +2
The position operator in a Bloch representation acquires a gauge correction in the momentum space on top of the canonical position, which is called the anomalous position. We show…
Ab initio investigation of laser-induced ultrafast demagnetization of L1 FePt: Intensity dependence and importance of electron coherence
M. S. Mrudul, Peter M. Oppeneer
We theoretically investigate the optically-induced demagnetization of ferromagnetic FePt using the time-dependent density functional theory (TDDFT). We compare the demagnetization…
Magneto-Optical Detection of the Orbital Hall Effect in Chromium
Igor Lyalin, Sanaz Alikhah, Marco Berritta +2
The orbital Hall effect has been theoretically predicted but its direct observation is a challenge. Here, we report the magneto-optical detection of current-induced orbital accumul…
