• Use of continuous wave and pulsed electron spin resonance techniques to study spin dynamics and materials issues in silicon doped with n - type impurities such as phosphorus;
  • The studies will involve both bulk doped and ion implanted samples, as well as the fabrication of devices on a submicron scale;
  • Low temperature (millikelvin) nuclear orientation and nuclear magnetic resonance will be applied to beta-ray emitting 32P in these systems to study and manipulate nuclear spin polarisation.


Ternary rare-earth intermetallic compounds are important from both theoretical and applied points of view. These compounds usually contain a transition element and a metalloid element, in addition to the rare-earth, and this combination allows us to study the role played by the f-d-p electrons in determining the magnetic stucture of a compound. We can also probe the fundamental magnetic exchange and crystal-field interactions across a series of related compounds.


Coherent transient experiments, including optical free induction decay, photon echoes and optical nutation, facilitate an understanding of subtlest details of electronic structures in the solid state. The project aims to investigate the application of coherent transients in chemically interesting systems, such as coordination compounds, by laser-frequency switching of semiconductor (diode) lasers.
