We study the loss of magneto-optic contrast in nickel, response to excitation by a short laser pulse, as function density. Our measurements picosecond and subpicosecond regime show saturation at high densities. conclude that spin relaxation is incomplete on this time scale, explain its terms collapse Stoner gap due band filling effects.
Ultrafast optical excitation of a ferromagnet/antiferromagnet (Ni/FeF2) exchange bias bilayer produces novel magnetization dynamics unlike ever observed before. An unexpected precession the magnetization, in reverse magnetic fields that exceed bias, originates from reorientation frustrated spins at interface. As laser-excited interface approaches blocking temperature, an reversal can also be induced with single pulse, showing not only ferromagnet but antiferromagnet is strongly affected by...
The brown alga Padina (Dictyotales, Ochrophyta) is found worldwide, predominantly in tropical to subtropical waters. Due their similar appearances, distinguishing between different species challenging. Historically, morphological characteristics such as the degree of calcification and thallus color were primary methods for identifying differentiating species, which often led misidentifications. advent molecular-aided taxonomic identification has allowed more reliable classification species....
We show saturation of the sub-picosecond demagnetization in nickel at high excitation densities, conclude that spin relaxation is incomplete, and associate with collapse Stoner gap due to band filling effects.
