Description

Recently, Xiang and Wheatley extended our proximity coupling SN model of the (S) CuO{sub 2} plane and (N) CuO chain layers in YBCO compounds, using the single particle bands {epsilon}{sup 0}{sub 1k} = -t(cos k{sub a} + cos k{sub b}) - {mu}{sub 1} and {epsilon}{sup 0}{sub 2k} = -t{sub 2y}cos k{sub b} - {mu}{sub 2}, respectively. Although we showed that it was possible to fit the penetration depth {lambda}{sub ab}(T) in twinned YBCO with either s- or d-wave pairing and both bands free-particle-like, they claimed that: (1) It is impossible to fit the quasi-linear {lambda}{sub a}(T) in untwinned YBCO without ... continued below

Although we showed that it was possible to fit the penetration depth {lambda}{sub ab}(T) in twinned YBCO with either s- or d-wave pairing and both bands free-particle-like, they claimed that: (1) It is impossible to fit the quasi-linear {lambda}{sub a}(T) in untwinned YBCO without order parameter line nodes, such as for d{sub x2-y2} pairing. (2) Even d-wave SN fits to the {lambda}{sub a,b,c} data are inferior to those obtained from a model of d-wave interlayer pair tunneling (DIPT). We remark that their claim is false, and ignores other data favoring proximity coupling.
