The dependences of the longitudinal resistance and the static magnetic susceptibility on the magnetic field applied perpendicularly to the plane of an ultranarrow silicon quantum well confined by {delta} barriers heavily doped with boron demonstrate the high-temperature Shubnikov-de-Haas and de-Haas-van-Alphen oscillations in low magnetic fields. The results are indicative of the implementation of the high-field approximation {mu}B Much-Greater-Than 1 under these conditions due to the small effective mass of two-dimensional heavy holes, which is confirmed by measurements of temperature dependences of the de-Haas-van-Alphen oscillations.
