Fig. 4: RRR dependence of the transport phenomena in SrRuO3.
From: Quantum transport evidence of Weyl fermions in an epitaxial ferromagnetic oxide
a RRR dependence of the MR (ρxx(B) − ρxx(0 T))/ρxx(0 T) measured at 2 or 2.3 K. When RRR > 19.4, the positive MR, which is one piece of experimental evidence of the Weyl fermions in SrRuO3, clearly emerges. b RRR dependence of the MR (ρxx(B) − ρxx (0 T))/ρxx (0 T) at B = 9 T and T = 2 or 2.3 K. c Diagram of the RRR dependence of TC, TF, and TW, which are shown as green stars, blue circles, and red triangles, respectively.
