Abstract
The effect of pressure on the B-T phase diagram of alpha-(BEDT-TTF)(2)KHg(S CN)(4) is studied. The measured phase lines can be well described by a rece nt model of a charge-density wave system with varying nesting conditions. A remarkable increase of the transition temperature with magnetic field is f ound in a certain pressure and field range. We associate this result with a dramatic enhancement of the orbital effect of magnetic field due to a dete rioration of the nesting conditions by pressure. Furthermore, we present da ta which can be interpreted as a first sign of field-induced charge-density waves.
