Аннотация:
Angular oscillations of magnetoresistance of a layered organic metal alpha -(BEDT-TTF)<sub>2</sub>MHg(SCN)<sub>4</sub> with M=Rb have been studied at temperatures below the electronic phase transition. The derived superstructure is found to be very similar, both qualitatively and quantitatively, to that reported earlier for the salt with M=Tl. A minor series of oscillations is observed, which is the mirror reflection of the main oscillations against the (a, 2b+c)-plane. The data obtained for M=K reveal significant quantitative differences from the Rb and Tl compounds.
