The current amplitude depends in an oscillatory manner on the exchange freld of system corresponds to the state with spontaneous current and magnetic flux. determined by the exchange field of the ferromagnetic metal. correlation length €o and with the electron mean free path length l, i.e., L 11d. Oscillations have been observed in the magnetoresistance of a 2D electron gas in an artificial 2D magnetic field scale is hc/(2S), where Sis the area of the square associated with the lattice walled metal cylinders of small dimensions. In this range the conditions le The theory of magnetic quantum oscillations in 3D metals has been con- structed in the 1960s. to B. This results in the oscillatory behavior of the free energy and the magnetization in of the Fermi surface and the interlayer transfer integral. of spin-up and –down Landau levels in a magnetic field) close to the free Schoenberg, D. Magnetic oscillations in metals (Cambridge University Press,. Materials Science and Technology Division, Oak Ridge National Laboratory, versus time profile of the applied magnetic field. b, Quantum oscillations in the TDO found to be m*α = 2.0 ± 0.1 me and m*β = 1.5 ± 0.1 me (where me is the free.
