Microstructure-Controlled Magnetic Properties of Annealed FeCo Nanowires: The Key Role of Crystallinity and Defects
The magnetic properties of FeCo nanowires are determined by their microstructure. By annealing as-deposited nanowires in reductive and oxidative atmospheres, we obtain two distinct microstructural states: a highly crystalline FeCo alloy phase and a CoFe 2 O 4 spinel phase derived from complete transformation of...
