Research Interests

The research interests of David E. Laughlin have centered on the investigation of phase transformations and the structure of materials by means of transmission electron microscopy. He has studied spinodal decomposition and ordering processes in several aluminum, copper and nickel based alloys as well as in III-V compounds by detailed analysis of their microstructure as well as electron diffraction patterns. Since 1986 he has been investigating the magnetic properties and microstructure of soft magnets (HITPERM), hard magnets (FePt and CoPt) and magnetic thin films for recording media and heads.
