Yg. Arapov et al., SPIN SPLITTING OF MAGNETORESISTANCE OSCILLATIONS AND QUANTUM HALL-EFFECT IN GE GE1-XSIX SUPERLATTICES IN AN OBLIQUE MAGNETIC-FIELD/, JETP letters, 59(4), 1994, pp. 245-250
A substantial change in the pattern of magnetoresistance oscillations
and the quantum Hall effect upon a change in the orientation of the ma
gnetic field with respect to the axis of the heterostructure has been
observed in multilayer p-Ge/Ge1-xSix heterostructures (x congruent-to
0.3). The effects observed result from the complex structure of the sp
ectrum of the 2D hole gas. They are associated with a transformation o
f this spectrum in an oblique magnetic field.
