Abstract

In this paper, we describe a method that uses Larmor precession of a neutron's spin to encode information about the direction of the neutron's path. We show that neutron spin echo (NSE) may be used to separate specular and diffuse reflection from the surface of a sample and to obtain information about the in-plane structure of thin films or interfaces. In the implementation discussed here, thin magnetic films of permalloy deposited on silicon substrates are used as Larmor precession devices that are both compact and well-defined geometrically and magnetically.
