The anomalous magnetoresistance of the simple metals is considered to be one of the outstanding unsolved porblems in metal physics. These metals, of which potassium is the archetype, have a transverse electrical magnetoresistance which increases linearly with the applied magnetic field. This is in strong disagreement with the semiclassical theory of transport in metals, which, for these metals, predicts a saturating (field independent) electrical magnetoresistivity. Many different approaches have been investigated in an attempt to explain the linear magnetoresistivity, including both intrinsic and extrinsic theories. It has recently been shown that a linear electrical magnetoresistivity of the correct order of magnitude can be obtained by considering the conductivity to be inhomogeneous. These ideas are examined, insofar as they apply to potassium, in the light of the transverse and longitudinal electrical magnetoresistivity data and in the light of recent measurements of the other transport coefficients of potassium (the Hall and Righi‐Leduc coefficients and the transverse and longitudinal thermal magnetoresistivity). We conclude that inhomogeneous conduction is not a likely cause of the magnetoresistance anomalies.
