Abstract : The primary scientific results and ongoing research resulting from the Air Force Grants are summarized. Completed work includes a detailed study of Alfven-wave velocities in pure bismuth that resolves a number of discrepancies in the literature; theoretical studies of Alfven-wave attenuation in pure and doped bismuth, experimental work showing how to obtain numerical relaxation times (including quantum effects) from Alfven-wave data; and the development of an extremely sensitive technique for the measurement of energy loss in superconductors. Ongoing work generated by these grants includes low frequency energy loss in superconductors, studies of Alfven-wave attenuation in bismuth and doped bismuth, Alfven-wave velocities in doped bismuth, and heat capacity studies as a function of magnetic field in pure bismuth. Seven completed papers and several in preparation are listed. (Author)
