Multiband electronic transport in α-Yb1₋xSrx AlB4 [ x = 0, 0.19(3)] single crystals
Abstract
Here we report on the evidence for the multiband electronic transport in α- YbAlB4 and α-Yb0.81(2)Sr0.19(3)AlB4. Multiband transport reveals itself below 10 K in both compounds via Hall effect measurements, whereas anisotropic magnetic ground state sets in below 3 K in α-Yb0.81(2)Sr0.19(3)AlB4. Our results show that Sr2+ substitution enhances conductivity, but does not change the quasiparticle mass of bands induced by heavy fermion hybridization.
