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…
Microscopic effect of spin-lattice couplings on dynamical magnetic interactions of a skyrmion system PdFe/Ir(111)
Banasree Sadhukhan, Anders Bergman, Johan Hellsvik +2
PdFe/Ir(111) has attracted tremendous attention for next-generation spintronics devices due to existence of magnetic skyrmions with the external magnetic field. Our density functio…
Resonant Soft X-Ray Scattering on LaPtSi
Deepak John Mukkattukavil, Johan Hellsvik, Anirudha Ghosh +15
X-ray absorption (XAS) and Resonant Inelastic X-ray Scattering (RIXS) spectra of LaPtSi single crystal at the Si L and La N edges are presented. The data are interpreted in…
Spin-lattice couplings in two-dimensional CrI from first-principles study
Banasree Sadhukhan, Anders Bergman, Yaroslav O. Kvashnin +2
Since thermal fluctuations become more important as dimensions shrink, it is expected that low-dimensional magnets are more sensitive to lattice distortions and phonons than bulk s…
