Local electron-electron interaction strength in ferromagnetic nickel determined by spin-polarized positron annihilation
We employ a positron annihilation technique, the spin-polarized two-dimensional angular correlation of annihilation radiation (2D-ACAR), to measure the spin-difference spectra of ferromagnetic nickel. The experimental data are compared with the theoretical results obtained within a combination of th...
