Resolving magnetic order and dynamics with polarized neutron scattering: a practical guide to longitudinal polarization analysis
Neutron scattering provides microscopic information on magnetic order and spin dynamics. Most experiments, however, use unpolarized neutrons and do not fully exploit the information carried by the neutron spin. Longitudinal polarization analysis (LPA), established in the pioneering work of Moon, Riste, and Koehler at O...
