摘要: In Section 1.1 are listed the theoretical limiting conditions which can be defined in study of galvanomagnetic effects metals. present chapter we shall give a survey theories have been developed for two most important these conditions: high- and low-field limits. These considered separately this 2.2, respectively. 2.3 contains description, both cases, two-band model conduction. Originally introduced to account magnetoresistance free-electron metal, has frequently applied properties metals, no interpretation Hall effect data would complete without some consideration it.
