N2 - By using a sensitive superconducting cavity resonator, we measure the temperature dependence of in-plane microwave penetration depth λab in underdoped single crystals of the iron-pnictide superconductor PrFeAsO1?y (Tc ∼ 35 K). At low temperatures, λab(T ) shows very flat temperature dependence, which indicates that the superconducting gap function Δ(k) is non-zero all over the Fermi surface.
