(a) Microwave transmittance of a CPW resonator at at two fixed temperatures , , with ; (b) difference of the traces in (a) (symbols) that is proportional to the total LSM PR, along with the inductive (solid line) and resistive (dashed line) components obtained using Eqs. (1). The symmetry of the resistive component and asymmetry of the inductive component relative to is clearly visible.
(a) LSM reflectivity map showing the patterned YBCO edge and twinned structure of the LAO substrate (highlighted by dark rectangles). Total HF photoresponse in the YBCO film taken simultaneously in the same area as (a). Arrows indicate sections A and B showing a large difference in LSM PR and selected for detailed analysis. Note that the largest PR comes from points where the twin domain block edges cross the film edge.
Gray-scale representation of frequency-dependent LSM PR taken on a long line scan at sections (a) A and (b) B of Fig. 2 between 5.54 and . The corresponding [(c) and (d)] normalized to positive maximum amplitude frequency profiles taken at , 175, and showing different decays of LSM PR in the YBCO film due to the influence of twin domains.
(Color online) 2D LSM images of (a) inductive and (b) resistive components of LSM PR in , extracted using Eqs. (2) from the data in Fig. 2.
