We report measurements of the in-plane London penetration depth λ in single crystals of the α−PdBi2 superconductor—the α-phase counterpart of the putative topological superconductor β−PdBi2, down to 0.35 K using a high-resolution tunnel-diode-based technique. Both λ and superfluid density ρs exhibit...
