Abstract

We study the dynamical properties of a hugely hysteretic magneto-resistance in epitaxially formed silicide nanowires, and propose a model for this remarkable effect in which it is attributed to the collective interactions among interfacial spins associated with dangling bonds. According to our model, the dynamic character of this effect reflects a competitive tendency for the interfacial spins to align in different collective configurations (random, ordered, and multi-domain). Our work thus provides a dramatic demonstration of how the collective interactions among interfacial spins can modify the properties of nonmagnetic nanostructures.
