2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/21743We study shot noise and cross correlations in a four terminal spin-valve geometry using a Boltzmann-Langevin approach. The Fano factor (shot noise to current ratio) depends on the magnetic configuration of the leads and the spin-flip processes in the normal metal. In a four-terminal geometry, spin-flip processes are particular prominent in the cross correlations between terminals with opposite magnetization.4 pages, 3 figuresMesoscale and Nanoscale PhysicsStatistical Mechanicstext
