The Rashba effect is one of the most striking manifestations of spin-orbit coupling in solids, and provides a cornerstone for the burgeoning field of semiconductor spintronics. It is typically assumed to manifest as a momentum-dependent splitting of

Quasiparticle Mass Enhancement and Temperature Dependence of the Electronic Structure of Ferromagnetic SrRuO3 Thin Films

Autor: Shai, D. E., Adamo, C., Shen, D. W., Brooks, C. M., Harter, J. W., Monkman, E. J., Burganov, B., Schlom, D. G., Shen, K. M.

Publikováno v: Phys. Rev. Lett. 110, 087004 (2013)

We report high-resolution angle-resolved photoemission studies of epitaxial thin films of the correlated 4d transition metal oxide ferromagnet SrRuO3. The Fermi surface in the ferromagnetic state consists of well-defined Landau quasiparticles, exhibi

Temperature dependence of the electronic structure and Fermi-surface reconstruction of Eu(1-x)Gd(x)O through the ferromagnetic metal-insulator transition

Autor: Shai, D. E., Melville, A. J., Harter, J. W., Monkman, E. J., Shen, D. W., Schmehl, A., Schlom, D. G., Shen, K. M.

Publikováno v: Phys. Rev. Lett. 108, 267003 (2012)

We present angle-resolved photoemission spectroscopy of Eu(1-x)Gd(x)O through the ferromagnetic metal-insulator transition. In the ferromagnetic phase, we observe Fermi surface pockets at the Brillouin zone boundary, consistent with density functiona

Determination of total x-ray absorption coefficient using non-resonant x-ray emission

Autor: Achkar, A. J., Regier, T. Z., Monkman, E. J., Shen, K. M., Hawthorn, D. G.

Publikováno v: Scientific Reports 1, 182 (2011)

An alternative measure of x-ray absorption spectroscopy (XAS) called inverse partial fluorescence yield (IPFY) has recently been developed that is both bulk sensitive and free of saturation effects. Here we show that the angle dependence of IPFY can
