Spin-orbit hybridization points in the face-centered-cubic cobalt band structure

Linear magnetic dichroism is observed in spin-, time-, and energy-resolved two-photon photoemission from valence bands of epitaxial fcc cobalt on Cu(001). With image-potential states as spectator states we identify initial bulk and surface states with minority spin character as the source for dichroic intensities and apparent dichroic lifetimes. Excellent agreement with ab initio fully relativistic calculations of the cobalt fcc band structure allows us to precisely determine spin-orbit hybridization points close to the Fermi level. These spin hot spots enhance spin-flip scattering by several orders of magnitude and are therefore assumed to be crucial in ultrafast demagnetization.     

Versatile Reagent Ph3As(OTf)2: One‐Pot Synthesis of [P7(AsPh3)3][OTf]3 from PCl3

Compound Ph₃As(OTf)₂ as a pentacoordinated As^V Lewis acid readily forms dicationic Lewis acid/base adducts upon addition of various Lewis bases. It also represents a stronger chloride‐abstracting agent than Me₃SiOTf and facilitates the reductive coupling of PCl₃ in the presence of AsPh₃ to the unprecedented cation [P₇(AsPh₃)₃]³⁺ as triflate salt. This crystallographically characterized nortricyclane‐type cation represents a P₇R₃‐derivative with the most electron‐withdrawing substituents, resulting in a pronounced effect on the structural parameters of the P₇ core.
