摘要：

We discuss two topics on the phenomena depending on the magnetic field orientation in low-dimensional conductors: (1) Angular dependence of field-induced spin-density-wave (FISDW) in quasi-one-dimensional (Q1D) conductors, and (2) angular-dependent magnetoresistance oscillation (Yamaji oscillations) in quasi-two-dimensional (Q2D) conductors without coherent interlayer coupling. The threshold fields of FISDW transition in an organic Q1D conductor (TMTSF)(2)ClO4 shows sharp decreases at Lebed's magic angles. We extend the "standard theory" of FISDW for the three-dimensional system, and try to explain this feature. We prepared a series of GaAs/AlGaAs superlattices with various interlayer couplings, and experimentally show that the Yamaji oscillations appear even in the Q2D system without coherent interlayer coupling.
