Sažetak
The transverse and planar magnetoresistance MR in a monocrystalline germanium with charge carrier of 1.7 x 1019 cm-3 has been measured at 77 K and 313 K. The measurements were done under a weak electric and magnetic fields. It was found that MR exibits two types of anomalous effects. At 77 K the variation of MR with rotating angle θ between the directions of both H and I is very strong, but at 313 K there is no considerable change. This phenomena may be attributed to the dynamical behaviour of the charge carriers, due to the applied magnetic field.
