Transition temperature of YBaCuO

  1. May 8, 2008 #1
    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!
