TL;DR: Using time-resolved single-shot pump-probe microscopy the mechanism and the time scale of all-optical magnetization reversal by a single circularly polarized 100 fs laser pulse are unveiled and it is demonstrated that for a 5 microm domain the magnetic information can be recorded and readout within 30 ps, which is the fastest "write-read" event demonstrated for magnetic recording so far.

TL;DR: In this paper, the authors present results of detailed experimental and theoretical studies of all-optical magnetization reversal by single circularly-polarized laser pulses in ferrimagnetic rare earth transition metal alloys.

TL;DR: Comparison to numerical simulations of thermal magnonic spin currents yields qualitative agreement for the thickness dependence resulting from the finite magnon propagation length and at low temperature, even quantitative agreement with the simulations is found.

TL;DR: It is shown that magnonic spin currents caused by temperature gradients lead to spin transfer torque effects, which can drag a domain wall in a ferromagnetic nanostructure towards the hotter part of the wire.

TL;DR: In this article, two stochastic forms of the Landau-Lifshitzitz-Bloch equation are discussed and compared with the Boltzmann distribution at high temperatures.
