Under laser illumination it is possible to drive a ferromagnet to lose its magnetization. While this process can be rapid, remagnetization following this is slower, due to the universal critical slowing down near the phase transition. Here, Remy et a

International audience; Terahertz (THz) emission from magnetic films has recently become an important characterization tool of spintronic properties, particularly since no patterning is required. One such property of interest is the spin-current atte

Differentiating Contributions of Electrons and Phonons to the Thermoreflectance Spectra of Gold

Autor: Kexin Liu, Jon Gorchon, Richard Wilson, Xinping Shi, Sinisa Coh, Ramya Mohan, Frank Angeles

To better understand the many effects of temperature on the optical properties of metals, we experimentally and theoretically quantify the electron vs. phonon contributions to the thermoreflectance spectra of gold. We perform a series of pump/probe m
