Title:
Spin-Resolved Fermi Surface of the Localized Ferromagnetic Heusler Compound ${\mathrm{Cu}}_{2}\mathrm{MnAl}$ Measured with Spin-Polarized Positron Annihilation 
Abstract:
We determined the bulk electronic structure of the prototypical Heusler compound Cu2MnAl by measuring the angular correlation of annihilation radiation using spin-polarized positrons. To this end, a new algorithm for reconstructing 3D densities from projections is introduced that allows us to corroborate the excellent agreement between our electronic structure calculations and the experimental data. The contribution of each individual Fermi surface sheet to the magnetization was identified, and...    »
