We report on the evidence for the multiband electronic transport in α-YbAlB 4 and α-Yb 0.81 (2) Sr 0.19 (3) AlB 4. 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-Yb 0.81 (2) Sr 0.19 (3) AlB 4. Our results show that Sr 2+ substitution enhances conductivity, but does not change the quasiparticle mass of bands induced by heavy fermion hybridization.
