FIG. 1.

(Color online) Normalized differential conductance versus bias voltage spectrum taken on a Pb/CrO2 point-contact junction at different temperatures. Open symbols correspond to the spectral data, and solid lines are fits using the BTK model.

Image of FIG. 2.
FIG. 2.

(Color online) Normalized conductance spectrum measured on a Au film using a YBCO tip at 4.2 K. Right inset is a plot of the unnormalized spectrum showing the linear background which is characteristic of YBCO.

Image of FIG. 3.
FIG. 3.

(Color online) Normalized conductance spectrum measured on a CrO2 film using a YBCO tip at 4.2 K. Insets show the unnormalized differential conductance spectra taken at 4.2 K (right) and at 100 K (left). Open symbols represent the data while solid lines are a polynomial fit to the background. Arrows indicate spectral kinks, whose locations are consistent with the superconducting gap maximum for YBCO.

Image of FIG. 4.
FIG. 4.

(Color online) Comparison of the normalized conductance spectra taken on YBCO/Au (circles) and YBCO/CrO2 (squares) at 4.2 K. Left inset shows various spectra calculated using the spin-dependent d-wave BTK model, for three junctions oriented normal to the ab-plane at Z = 1: upper three curves are for P = 0, with the junction normal rotated by 0, π/12 and π/4 (top to bottom) from the d-wave node axis; the lower three curves are for P = 0.9 at the same three junction angles. Right inset shows two angle-averaged spectra (P = 0 for upper, P = 0.9 for lower), each averaged within a Gaussian envelope of width π/6 about the d-wave node axis, to simulate our nominally-oriented (110) YBCO tip junctions.
