Transition temperature of YBaCuO

Hi,

Sorry to be a pain but I can't find what I'm looking for on the internet and our lab is locked.

I need to know the accepted transtition temperature for Yttrium Barium Copper Oxide (YBa2Cu3O(7-x)

Is anyone able to give me a figure or ideally point me in the direction of a web resource that has it?

I know this depends on exactly how much oxygen is in the sample, but is there a "general" value? My sample has T=91K but I'd like to compare this to what would be expected.

Kind Regards

Luke

The accepted bulk value of optimally doped YBCO is 92K (some report 93K, but more accurate measurements tend to give a value closer to 92K).

91K would be a good value for e.g. a relatively thick film.
 
91K is a reasonable value for a bulk sample, but high for a thin film.
 
Thanks guys,

This was determined for just under 1g of YBaCuO, so I'm fairly happy with that result.

Much Appreciated!
 
From the BCS theory of superconductivity is well known that the superfluid density smoothly decreases with increasing temperature. Annihilated superfluid carriers become normal and lose their momenta on lattice atoms. So if we induce a persistent supercurrent in a ring below Tc and after that slowly increase the temperature, we must observe a decrease in the actual supercurrent, because the density of electron pairs and total supercurrent momentum decrease. However, this supercurrent...
Hi. I have got question as in title. How can idea of instantaneous dipole moment for atoms like, for example hydrogen be consistent with idea of orbitals? At my level of knowledge London dispersion forces are derived taking into account Bohr model of atom. But we know today that this model is not correct. If it would be correct I understand that at each time electron is at some point at radius at some angle and there is dipole moment at this time from nucleus to electron at orbit. But how...
