How can Weyl semimetal materials be identified through electrical and magnetotransport measurements? Can magnetotransport measurements provide evidence to demonstrate the Weyl semimetal behavior of a material?
Yes, magnetotransport measurements provide evidence of Weyl nodes. Please see the attached references.

Sir, in which configuration does negative magnetoresistance occur, with the magnetic field in the plane or out of the plane? Because in our sample, we observe negative non-saturating magnetoresistance when an external magnetic field is applied perpendicular to the plane/current. So, is this a characteristic feature of Weyl materials?
