In the present work the investigation of the effect of YBa2Cu3O7-x complex
compounds thin films on the mesomorphic, morphologic and orientational prop
erties of lyotropic nematics have been carried out. The thin films of YBa2C
u3O7-x lead to an increase in number of morphologies of investigated nemati
cs and promote the obtaining of tilted oriented and homeotropic textures of
these nematics.
The coating of YBa2Cu3O7-x thin films by inverted cylindrical DC magnetron
sputtering system has been shown in this work to be a useful method for obt
aining oriented textures of lyotropic nematics. (C) 2000 Elsevier Science S
