 Fig 3 shows the reciprocal magnetic flux density 1/"B""i" of the 10th to 14th minima of a Bi2Se3 sample.The slope of 0.00618/T as obtained from a linear fit yields the electron density "n"

Shubnikov-de Haas oscillations can be used to map the Fermi surface of electrons in a sample, by determining the periods of oscillation for various applied field directions.The effect is related to the de Haas–van Alphen effect, which is the name given to the corresponding oscillations in magnetization.
