Fig. 1: Linear and sub-linear magnetoresistivity in Pd3In7.
a Sketch depicting the planes of rotation of the magnetic field μ0H, from I⊥μ0H to I∥μ0H (longitudinal magnetoresistivity configuration or LMR), as a function of the angle ϕ. I is the electrical current. b Sketch illustrating sample rotation under μ0H, where I is kept ⊥μ0H and the angle θ is varied (conventional magnetoresistivity configuration or CMR) c Electrical resistivity ρxx of Pd3In7 as a function of the temperature T. For T > 50 K, ρxx displays a linear dependence on T (red line is a linear fit), while ρxx exhibits a quadratic behavior (cyan line is a fit) for T≤50 K. Inset: ρxx in a magnified scale illustrating the residual resistivity ρ0 ≃ 110 nΩ cm. d Hall conductivity σxy as a function of μ0H, displaying a minimum at μ0H0 = 0.84 T. e Magnetoresistivity MR as a function of μ0H for 3 T ≦ μ0H ≦ 41.5 T. Blue and black lines correspond to the experimental data for θ = 0∘ and θ = 35∘, respectively. Dashed magenta line corresponds to a linear fit of the θ = 0∘ data for the entire field range, while red dashed line indicates the deviation of the black line with respect to linear behavior. Inset: MR as a function of μ0H, for fields up to μ0H = 9 T. Red line is a fit of the data for μ0H < 4 T to MR = d1 + d2(μ0H) + \({d}_{3}{({\mu }_{0}H)}^{2}\), where d2 and d3 are coefficients of the linear and quadratic terms, respectively.
