Summary on Grant Application Form |

A novel optical heterodyne technique for magnetic resonance spectroscopy will be developed in which the sensitivity is several orders of magnitude greater than in conventional methods, thus making it possible to study specimens in which the number of magnetic centres is extremely small. The technique makes use of the coherent changes induced in a scattered laser beam when magnetic resonance occurs and takes advantage of recent advances in optical detectors of fast response. It will be applied, for the first time, to studies of semiconductor heterostructures (including quantum wells and self-organised systems) and, in parallel, to investigations of biophysical chromophores (notably the catalytic transition ion centres of enzymes). For the former, the technique will provide a greater understanding of the profound effects that factors such as quantum confinement, strain, piezoelectric fields and compositional disorder have on the magnetic moments of electrons and holes. For the enzymes, the experiments will provide considerable information about the locality, charge state and bonding of the active ions that will be related to their biochemical functions. The project is firmly rooted in the physics that underlies magnetic resonance and magneto-Raman scattering, but will have wide applications in both physics and the life sciences.
