TL;DR: First-principles calculations well describe both low α and large K(u) for these alloys, and the damping constant α, characterizing macroscopic spin relaxation and being a key factor in spin-transfer-torque systems, is not larger than 0.008 for the δ=1.46 (0.88) film.

TL;DR: The magneto-Seebeck effect as mentioned in this paper is observed when a magnetic configuration changes the charge-based Seebeck coefficient, which can be measured as a voltage change directly without conversion of a spin current.

TL;DR: It is proposed that this characteristic of femtosecond optical excitation of half-metals enables the establishment of a novel and fast characterization tool for this highly important material class used in spin-electronic devices.

TL;DR: In this article, the authors review the need for multiscale modeling to address the processes starting from electronic excitation of the spin system on the picometer length scale and sub-femtosecond time scale, to spin wave generation, and towards the modeling of ultrafast phase transitions that altogether determine the response time of the ferromagnetic system.
