      Disorder-induced vortex phase transition in untwinned YBa2Cu3O7-δ crystal 

      Giller, D.; Giapintzakis, John; Shaulov, A.; Yeshurun, Y. (2000)
      Local magnetic measurements in an untwinned YBa2Cu3O7-δ crystal as a function of temperature, field and time reveal anomalies occurring along the same line BSS(T) in the field-temperature plane. We identify BSS(T) as a ...

      Progress in photothermal microscopy of YBa2Cu3O7-x 

      Studenmund, W. R.; Fishman, I. M.; Kino, G. S.; Giapintzakis, John (1998)
      We present recent differential optical reflectivity (DOR) measurements obtained at 633 nm (2.OeV), 780 nm (1.6eV), 1064 nm (1.16eV), and 1310nm (0.95 eV). We discuss calibration techniques which can correct for variations ...
