First-principles theory of laser-induced dynamics on the magnetic Dy2Ni2(DMF) complex — •Bharadwaj C. Mummaneni, Stefan Sold, Georgios Lefkidis, and Wolfgang Hübner — Department of Physics and Research Center OPTIMAS, Technische Universität Kaiserslautern, Kaiserslautern, Germany

We study the functional role of d and f electrons in the tetra-heteronuclear Dy2Ni2(DMF) magnetic complex, which harbors a great potential as a magnetic-logic-element building block in future nanospintronic devices [1]. We focus on the theoretical characterization of the magnetic properties and the laser-induced spin dynamics of the complex, which adopts a defect dicubane geometry and has a ferromagnetic electronic ground state [2].

The highly correlated electronic excited states are computed with the state-of-the-art equation-of-motion coupled-cluster method and the perturbative inclusion of spin-orbit coupling. We are able to theoretically explain the experimental electronic absorption spectrum, as well as several time-resolved differential absorption spectra, after two different pump pulses (at 300 and 400 nm, respectively).
