The critical behaviour of laser-induced changes in magnetic ordering is studied experimentally in two-dimensional zigzag antiferromagnets $XY$-like NiPS$_3$ and Ising-like FePS$_3$. To examine laser-induced dynamics in flakes of these compounds, we e

Charge transfer and asymmetric coupling of MoSe$_2$ valleys to the magnetic order of CrSBr

Autor: de Brito, C. Serati, Junior, P. E. Faria, Ghiasi, T. S., Ingla-Aynés, J., Rabahi, C. R., Cavalini, C., Dirnberger, F., Mañas-Valero, S., Watanabe, K., Taniguchi, T., Zollner, K., Fabian, J., Schüller, C., van der Zant, H. S. J., Gobato, Y. Galvão

Van der Waals (vdW) heterostructures composed of two-dimensional (2D) transition metal dichalcogenides (TMD) and vdW magnetic materials offer an intriguing platform to functionalize valley and excitonic properties in non-magnetic TMDs. Here, we repor

Ultrafast laser-induced spin-lattice dynamics in the van der Waals antiferromagnet CoPS3

Autor: Khusyainov, D., Gareev, T., Radovskaia, V., Sampathkumar, K., Acharya, S., Šiškins, M., Mañas-Valero, S., Ivanov, B. A., Coronado, E., Rasing, Th., Kimel, A. V., Afanasiev, D.

Publikováno v: APL Mater 11, 071104 (2023)

CoPS3 stands out in the family of the van der Waals antiferromagnets XPS3 (X=Mn, Ni, Fe, Co) due to the unquenched orbital momentum of the magnetic Co2+ ions which is known to facilitate the coupling of spins to both electromagnetic waves and lattice

Controlling the anisotropy of a van der Waals antiferromagnet with light

Autor: Afanasiev, D., Hortensius, J. R., Matthiesen, M., Mañas-Valero, S., Šiškins, M., Lee, M., Lesne, E., van der Zant, H. S. J., Steeneken, P. G., Ivanov, B. A., Coronado, E., Caviglia, A. D.

Force-free state in a superconducting single crystal and angle-dependent vortex helical instability

Autor: del Valle, J., Gomez, A., Gonzalez, E. M., Manas-Valero, S., Coronado, E., Vicent, J. L.

Publikováno v: Phys. Rev. B 95, 224510 (2017)

Superconducting 2H-NbSe2 single crystals show intrinsic low pinning values. Therefore, they are ideal materials with which to explore fundamental properties of vortices. (V, I) characteristics are the experimental data we have used to investigate the

Field dependence of the vortex core size probed by STM

Autor: Fente, A., Herrera, E., Guillamon, I., Suderow, H., Manas-Valero, S., Galbiati, M., Coronado, E., Kogan, V. G.

Publikováno v: Phys. Rev. B 94, 014517 (2016)

We study the spatial distribution of the density of states (DOS) at zero bias N(r) in the mixed state of single and multigap superconductors. We provide an analytic expression for N(r) based on deGennes' relation between DOS and the order parameter t
