Investigation of Tl2Ba2Cu1Ox (Tl-2201) properties is important as it provides access to the overdoped side of the superconducting dome. We are measuring the surface resistance of Tl-2201, Rs(ω,T), using a bolometric technique well established by our group. Experimentally separating the in- and out-of-plane components of Rs for Tl-2201, however, is challenging due to demagnetization effects. To account for this complication, we are measuring Rs of an isotropic replica sample of NbZr in two specific orientations where the field is parallel and perpendicular to the crystal plane. In this talk I will describe the modified bolometric technique, share the technical difficulties encountered in preparing the replica, and present the most up-to-date results.
