Weak‐field magnetoresistance skewness and galvanomagnetic measurements on the (001)‐plane of n‐type Ge single crystal
Weak‐field galvanomagnetic measurements were carried out at room temperature on a (001)‐circular flat sample of ann‐type Ge single crystal using the Van der Pauw‐Wasscher technique, with the magnetic field parallel and normal to the sample plane. Thus, the anisotropy which appears in the (001)‐plane of cubic crystals due to the magnetic field is investigated and the existence of the magnetoresistance skewness effect is established experimentally. This effect allows the determination of all the galvanomagnetic coefficients in a simple way. The new result concerning Ge is the negative sign of the rgr;1212coefficient which is attributed to the reverse rotation of the magnetoresistance.
