TL;DR: It is demonstrated that all-optical helicity-dependent switching (AO-HDS) can be observed not only in selected rare earth-transition metal alloy films but also in a much broader variety of materials, including RE-TM alloys, multilayers and heterostructures.

TL;DR: In this article, an EY-like mechanism based on electron-electron scattering has been proposed to explain time-resolved magneto-optical Kerr effect measurements on thin magnetic Co and Ni films, without reference to a ''phononic spin bath''.

TL;DR: In this paper, the authors demonstrate all-optical magnetization switching for different TbxCo1-x ferrimagnetic alloy composition and demonstrate alloptical switching for films with anisotropy fields reaching 6 T corresponding to anisotropic constants of 3x106 ergs/cm3.

TL;DR: In this article, all-optical magnetization switching for different TbxCo1−x ferrimagnetic alloy compositions using fs- and ps-laser pulses was demonstrated for films with anisotropy fields reaching 6'T corresponding to anisotropic constants of 3'×'106 ergs/cm3.

TL;DR: In this paper, the authors explore the dependence of ultrafast demagnetization dynamics in nickel through a survey of different laser intensities and ambient temperatures, and find that the fluence and the temperature dependence of the demagnetic transition from one-step to two-step dynamics are reproduced theoretically assuming only a single scattering mechanism coupling the spin system to the temperature of the electronic system.
