Critical exponents for the metal-insulator transition of 70Ge:Ga in magnetic fields
Abstract
We have measured the electrical conductivity of nominally uncompensated 70Ge:Ga samples in magnetic fields up to B=8 T at low temperatures (T=0.05-0.5 K) in order to investigate the metal-insulator transition in magnetic fields. The values of the critical exponents in magnetic fields are consistent with the scaling theories.
