R. Schneider et al., GROWTH FRUSTRATION OF YBACUO FILMS AT THE TRANSITION FROM A- TO C-AXIS ORIENTATION, Solid state communications, 89(1), 1994, pp. 81-85
Thin a-axis oriented YBaCuO films have been deposited in the self-temp
late procedure with the deposition temperature in the second step, T-s
, as a parameter. At T-s values around 790 degrees C the conditions fo
r a- and c-axis growth become similar leading to growth deterioration
by a frustration effect. This effect limits the maximum T-s values app
licable to ordering of a-axis films. In this series of experiments the
a-axis films with negligible c-axis content had T-c-values around 80
K.
