Galvanomagnetic and Thermomagnetic Effects: the Hall and Allied Phenomena

“…and cooled several times the . Bismuth in a Longitudinal Field As already noted, p. 159, Fae, Goldhammer, and Tomlinson observed that bismuth increased in resistance in a Fae^'92) discovered that antimony increased in resistance in both transverse and longitudinal fields.Goldhammer (^'3), 1887, found that antimony and also tellurium increased in resistance in both types of field.The measurements by Lenard (324)^1890, of the change in resistance of antimony and tellurium in a transverse field for direct and alternating currents are given in the table below. the above metals, paramagnetic and diamagnetic, are arranged according to the magnitude of the increase in re-resistance in a transverse magnetic field: Pt, Ag, Bi, Cd, Alt, Zn, Mg, Pd, invar, and manganin.The resistance of selenium in a transverse magnetic field was found by Amaduzzi (^5\ 1909, to increase.…”
