(a) Crystal structure of PdSn₄, (b) XRD pattern of PdSn₄ single crystal. The reflection (0l0) is the as-grown crystal face. The upper-right inset shows an optical image of a PdSn₄ single crystal. Typical size of the sample is 2 mm× 2 mm× 1 mm. (c) Energy dispersive spectra of PdSn₄ single crystal. (d) Temperature-dependent resistivity of PdSn₄ single crystal with current along the ac plane. (e) Temperature dependence of the fast Fourier transformed dHvA data for H∥b. Inset shows the raw dHvA data.
