Hall constant of thulium and lutecium at high temperatures

The Hall constant of thulium and lutecium has been studied at 80-1000 K. The method involving alternating magnetic field and alternative current of various frequencies was used for measurements. Measurement results show that at temperature growth in paramagnetic region the Hall constant decreases monotonously. A general characteristic of the Hall constant for all the heavy rare earth metals from gadolinium to lutecium has been presented based on the data obtained
