  Measuring the magnetoconductivity induced from impurities may help determine
the impurity distribution and reveal the structure of a Weyl semimetal sample.
To verify this, we utilized the Gaussian random disorder to simulate charged
impurities in a two-node Weyl semimetal model and investigate the impact of
charged impurities on magnetoconductivity in Weyl semimetals. We first compute
the longitudinal magnetic conductivity and find that it is positive and
increases proportionally with the parameter governing the Gaussian distribution
of charged impurities, suggesting the presence of negative longitudinal
magnetoresistivity (NLMR). Then we consider both the intravalley and
inter-valley scattering processes to calculate the induced transverse
magnetoconductivity in the model. Our findings indicate that both inter-valley
and intra-valley scattering processes play important roles in calculating the
transverse magnetoconductivity. The locations of Weyl nodes can also be
determined by magnetoconductivity measurements. This is possible if the
magnetic field strength and the density of charged impurities are known.
Alternatively, the measurement of magnetic conductivity may reveal the
distribution of charged impurites in a given sample once the locations of the
Weyl nodes have been determined. These findings can aid in detecting the
structure of a Weyl semimetal sample, enhancing comprehension of
magnetotransport in Weyl semimetals, and promoting the development of valley
electronics.
