Abstract
Measurements of the low temperature magnetoresistance of alpha-(BEDT-T TF)(2)KHg(SCN)(4) under uniaxial stress perpendicular to the BEDT-TTF molecular layers indicate that the density wave ground state is suppre ssed by 1.5 Kbar. The fundamental Shubnikov-de Haas frequency decrease s at an approximate rate of -20 tesla/Kbar and a slow, stress dependen t oscillation appears for stresses above 0.9 Kbar. These enhanced stre ss effects are discussed in light of the high sensitivity of the Fermi surface to small changes in the crystal structure.
