1/f resistance noise studies of the spin dynamics in two magnetic systems are described in this thesis. In chromium, 1 If noise was used as a probe to study spin density wave polarization dynamics. Measurements of the ...

The nature of l/f noise in semiconductors and metals has been analyzed in light of the information provided by some unique, empirically determined parameters. Measurements of the instantaneous resistivity fluctuation ...

9Be , 1OB, 11B, 12c, 24Mg , 25Mg , 26Mg and 27Al targets have been bombarded with the 3He beam from the University of Illinois cyclotron. Elastic scattering angular distributions have been obtained in the approximate ...

This thesis consists of two parts. The first part deals with the question of whether localized magnetic moments are present on the 3d atoms, Cr and Mn, when dilutely doped in Nb and V. The second part deals with the ...

In this thesis the use of the Unrestricted Hartree-Fock technique augmented by many body perturbation theory techniques and symmetry projection methods in the study of the energies of the excited states of atomic, molecular ...

We have measured the absolute 2H( 1 ,p )n angular distribution using the Illinois LASA detector at the Saskatchewan Accelerator Laboratory's tagged photon facility. Using 40 to 90 MeV photons, we aimed to measure the ...

Luminescent excitation spectra were measured for the F and M centers in KCl; in particular, for the F band, M band, and the M2 transition. In all 3 cases, the spectra were nearly double-Gaussian in shape, and the efficiency ...

It is generally accepted that many pulsating X-ray sources are rotating magnetic neutron stars undergoing accretion. The text of this thesis provides a historical introduction to four studies, contained herein as appendices, ...

Quantum Monte Carlo (QMC) is one of the most powerful methods for solving many body problems in Physics and Chemistry. MC sampling allows one to measure physical properties systems with very complicated wave functions that ...
