series of posts cataloguing how there are wide range of strongly correlated metals which exhibit magnetoresistance which is qualitatively different from the semi-classical orbital magnetoresistance seen in most metals due to the Lorentz force. For the latter the magnetoresistance is maximal (zero) for the current and magnetic field perpendicular (parallel) to each other.
The data above is taken from a paper reporting measurements on the quasi-one-dimensional metal Li0.9Mo6O17, which also exhibits other non-Fermi liquid properties.
The graph shows the magnetic field dependence (in Teslan) of the relative change in the interlayer resistance with the field and current parallel to one another. The different curves correspond to different temperatures, increasing from 3 K to 50 K, from top to bottom.
