TL;DR: This work presents the first materials specific ab initio theory of the magnetization induced by circularly polarized laser light in metals, and compute effective optomagnetic fields that correspond to the induced magnetizations and provide guidelines for achieving all-optical helicity-dependent switching.

TL;DR: The measurement of the interfacial spin accumulation induced by the spin Hall effect in Pt and W thin films using magneto-optical Kerr microscopy is reported and it is shown that the Kerr rotation has opposite sign in Ptand W and scales linearly with current density.

TL;DR: A complete multiscale model is developed which allows us to optimize the number of laser shots needed to switch the magnetisation of high anisotropy FePt nanoparticles and concludes that only angular momentum induced optically by the inverse Faraday effect will provide switching with one single femtosecond laser pulse.

TL;DR: In this article, the tradeoff between efficient coupling and decoherence due to broad-band colored noise (BBCN) is addressed, in the class of nanodevices based on the Cooper pair box (CPB) design.

TL;DR: In this paper, the femtosecond spin injection from an optically excited Ni top layer into an Au bottom layer using time-resolved complex magneto-optical Kerr effect (C-MOKE) measurements was investigated.
