We have studied a series of Nd/Y films and superlattices, grown by molecular beam epitaxy (MBE), using neutron, x-ray, and bulk magnetization techniques. These epitaxial Nd/Y systems are the first to be grown and studied ...

To understand the cause of the giant magnetoresistance effect, we have systematically investigated magnetothermopower, magneto-thermal conductivity and magnetoresistivity in both ferromagnetic/non-magnetic multilayers and ...

A new approach to the problem of X-ray edge singularities and peaks of many-body origin observed in the optical spectra is presented. We first establish the analogy between a system of one hole interacting with many electrons ...

In this thesis I study two separate topics in many-body physics. In the first part I consider many-body effects in the thermodynamic properties of Fermi liquids and of the electron-phonon system. Using normal liquid ('3)He ...

High-precision measurements of third sound velocities in atomically thin $\sp4$He films on Ar, Ne, CO$\sb2$, and H$\sb2$ substrates in the T = OK limit reveal a periodic structure not corresponding to whole layers. We ...

We measure for the first time the characteristics of vortex induced superfluid flow dissipation at temperatures well below the Kosterlitz-Thouless superfluid transition temperature. Our studies are with films of coverage ...

Single-crystal Si films have been grown on Si(001)2x1 substrates by UV-photostimulated atomic-layer epitaxy (ALE) from Si$\sb2$H$\sb6.$ The ALE deposition rate R per growth cycle remains constant at 0.43 monolayers (ML), ...
