Yg. Arapov et al., OSCILLATIONS OF THE MAGNETORESISTANCE IN STRESSED GE GE1-XSIX SUPERLATTICES SUBJECTED TO A TILTED MAGNETIC-FIELD/, Semiconductors, 27(7), 1993, pp. 642-647
The angular dependence of the oscillatory magnetoresistance pattern ex
hibited by stressed multilayer Ge/Ge1-xSix heterostructures in a tilte
d magnetic field has been studied. In the spin splitting region the os
cillation pattern depends strongly on the degree to which the conducti
ng layers of a heterostructure are stressed. The observed effects are
a consequence of the complex form of the hole spectrum in the valence
band of Ge, which is described by the Luttinger Hamiltonian.
