Abstract
de Haas-van Alphen experiments on alpha- (BEDT-TTF)(2)KHg(SCN)(4) in f ields of up to 60 T reveal oscillations of the beta frequency, a clear indication of magnetic breakdown at fields well above the kink transi tion. A study of the amplitude of the oscillations shows that the gap between the quasi-one-dimensional and quasi-two-dimensional Fermi-surf ace sheets is significantly smaller than predicted by band-structure c alculations. We consider the implications for the spin-density-wave ne sting and the quantum Hall effect. [S0163-1829(98)03735-7].
