Abstract
Nuclear spin-lattice relaxation measurements were performed on Go-based mag netic nanowires, in zero field and in 1 T applied field. A measurement meth od is developped that allows a confident interpretation of the experimental data. An enhanced relaxation due to a thermally activated phenomenon assoc iated to oxidation is reported for the first time in the nuclear magnetic r esonance of ferromagnetic systems.
