(author), Coronado, E. (author)CoPS<sub>3</sub> stands out in the family of the van der Waals antiferromagnets XPS<sub>3</sub> (X = Mn, Ni, Fe, and Co) due to the unquenched orbital momentum of the magnetic Co<sup>2+</sup> ions, which is known to facilitate the coupling of spins to both electromagnetic waves and lattice vibrations. Here, using a time-resolved magneto...journal article 2023

(author), Ivanov, B. (author), Caviglia, A. (author)Van der Waals magnets provide an ideal playground to explore the fundamentals of low-dimensional magnetism and open opportunities for ultrathin spin-processing devices. The Mermin-Wagner theorem dictates that as in reduced dimensions isotropic spin interactions cannot retain long-range correlations, the long-range spin order is stabilized by...journal article 2021

(author), Caviglia, A. (author)Resonant ultrafast excitation of infrared-active phonons is a powerful technique with which to control the electronic properties of materials that leads to remarkable phenomena such as the light-induced enhancement of superconductivity<sup>1,2</sup>, switching of ferroelectric polarization<sup>3,4</sup> and ultrafast insulator-to-metal...journal article 2021

(author)Ultrafast photodoping of the Mott insulators, possessing strong correlation between electronic and magnetic degrees of freedom, holds promise for launching an ultrafast dynamics of spins which cannot be described in terms of conventional models of ultrafast magnetism. Here we study the ultrafast laser-induced dynamics of the magnetic order in...journal article 2019

Afanasiev, D. (author), Ivanov, B. A. (author), Pisarev, R. V. (author), Kirilyuk, A. (author), Rasing, Th (author), Kimel, A. V. (author)Excitation of antiferromagnetic HoFeO<sub>3</sub> with a single 80 fs laser pulse triggers a first-order spin-reorientation phase transition. In the ultrafast kinetics of the transition one can distinguish the processes of impulsive excitation of spin precession, nucleation of the new domain and growth of the nuclei. The orientation of the...journal article 2017
