Study of Magnetic Structure of Multilayers

This work has been motivated by the strong
technological interest in spin-valve structures
exhibiting the effect of giant magnetoresistance.
This phenomenon has been widely utilized in a new
generation of magnetoresistive memory, reading heads
for magnetic disk drives, and field sensors. The
research has showed that the interfacial roughness
strongly depends on the conditions of sample
preparation. It also revealed a non-collinear
coupling of magnetization between the ferromagnetic
layers of the spin-valve samples. The signs of the
coupling constants have been determined from the
neutron reflectometry data using minimum energy
model for the relative orientations of
magnetization. In addition to the main topic of the book, the last chapter is dedicated to study of
ultracold neutron (UCN) storage anomaly. The
experiments have indicated a possibility of UCNs
temporarily adhering to the inner coating of the
trap and being released later back to the storage
container.
