摘要：

We show that a new fundamental period P-f of dHvA oscillations, which appears along with other ''forbidden'' combination frequencies in a multi-band canonical Fermi-liquid, is very robust with respect to a finite smearing of Landau levels and a background of non-quantized states. We analyse the possibility of measuring small Fermi surface pockets with the use of the ''forbidden'' frequencies. (C) 1997 Elsevier Science B.V.
