DESCRIPTION

For starters c axis vs B We have a lot of this, here there is Selva’s sample compared to old BZO SP and no BZO Sp. sample M3-609-1-MS norm to 12mm, thickness 2.15 um. The same on log-log scale. sample M3-594-1-MS norm to 12 mm thickness 1.5 um. SP26. SP27 (former 25). SP20. - PowerPoint PPT Presentation

For the above angular, maybe:

1 show that these with BZO wider

That exp fits for high fields

That GL fits for low fields-we have 1 T sometimesIf what Alex said is true, anizotropy for 1 T for NO BZO should be lower than for BZOI did not checked yet…

And maybe something about scaling, like starting from 1 T and vs B calculate how it departs from GLFor higher fields

Same data, vertical scale logIt seems that Zr samples have wider maxima than Y dopedFWHM shown in the legend are larger for Zr doped, indeed

I very like this, but this is MetOx

How macroscopic defects in substrate, coating copper etc etc influence growth, performance? Is there any correlation?
