C. Lamine et al., EFFECT OF HYDRAZINE HYDRATE ON SUPERCONDU CTOR COMPOUNDS AT HIGH CRITICAL-TEMPERATURES, Physica status solidi. a, Applied research, 155(1), 1996, pp. 195-198
In the present paper, we study the influence of hydrated hydrazine (N2
H4, H2O) on supra-conducting compounds of high critical temperatures:
YBa2Cu3O7-x (T-c approximate to 95 K) and (Bi1-xPbx)(2)Sr2Ca2Cu3O10 (2
223, 110 K). The experimental technics used are the X-ray diffraction
(XRD) and tile infrared spectroscopy (IS). These compounds have a lame
llar structure. X-rag diffraction studies showed a change of structure
and new vibrational modes were found by the infrared spectroscopy.
