DYNAMICS OF SIMULTANEOUS MEASUREMENTS OF HALL AND MAGNETORESISTANCE EFFECTS IN LIQUID METALS AND SEMICONDUCTORS

In the present paper the Hall measurement in the liquid state of metals, using two-frequency method, ac-dc method and simultaneous method will be described. The Hall effect has been measured in Hg and Ga, both solid and liquid state. We have also measured magnetoresistance and Hall effect in InSb single crystal in which magnetoresistance appears even in low magnetic field and Si in which magnetoresistance do not appear clearly. In order to investigate the magnetic field dependence of galvanomagnetic effects in metals (in solid and liquid state) and semiconductors, the measurement in high magnetic field up to ±9 [T] were also performed
