Fig. 3: Power law behavior of the magnetoresistivity of Pd₃In₇.

a Power law coefficient n, in MR \(\propto \alpha {({\mu }_{0}H)}^{n}\), as a function of the angle θ. Intriguingly, n reveals a minimum around θ = 60^∘. b Coefficient α as a function of θ. Notice how α increases by a factor ~3 as θ exceeds 60^∘. c Color plot of the power coefficient n at T = 0.35 K, extracted from the relation \(n=\partial \ln (\rho_{\text{xx}} -{\rho }_{0})/\partial \ln ({\mu }_{0}H)\), as a function of θ and μ₀H, for I⊥μ₀H throughout the whole angular range. d Color plot of the power law coefficient n at T = 0.38 K, as a function of ϕ and μ₀H, from ϕ = 0^∘, or I⊥μ₀H, to ϕ = 90^∘, or I∥μ₀H.
