Change of Resistance in Magnetic Fields

Nature volume 127, pages 336337 (07 March 1931) | Download Citation



UNTIL recently, the theory of conductivity put forward by Sommerfeld and Bloch did not succeed in explaining the change of resistance in magnetic fields. If R′ is the resistance in a magnetic field H, R that without magnetic field, then for weak fields the change of resistance ΔR=R′ - R follows theoretically as well as experimentally the law1
