Origin of superconductivity suppression in (Er1-xPrx)Ba2Cu4O8 studied by X-ray absorption spectroscopy

Chhikara, A.; Priolkar, K.R.; Sarode, P.R.; Prabhu, R.B. (X-ray spectroscopy and allied areas, Ed. by: S.K. Joshi, B.D. Srivastava and A.P. Deshpande. Narosa Publishing House, New Delhi. 1998; 150-152.)
Superconductivity suppression in (Er(1-x)Pr(x))Ba(2)Cu(4)O(8): An x-ray absorption spectroscopic study

Chhikara, A.; Priolkar, K.R.; Sarode, P.R.; Prabhu, R.B.; Narlikar, A.V. (Journal of Physics-Condensed Matter. 11(22); 1999; L229-L233.)

In this letter we report our measurements of Er and PrL(3) edges in Er(1-x)Pr(x)Ba(2)Cu(4)O(8), 0 less than or equal to x less than or equal to 0.6. The normalized L(3)-edge intensity is seen to closely follow the behaviour ...
T-C degradation in cuprate superconductors from the resistivity of Yba2(Cu(1-X)M(X))(4)O(8) for M=Fe and Ni

Lal, R.; Awana, V.P.S.; Pandey, S.P.; Yadav, V.S.; Varandani, D.; Narlikar, A.V.; Chhikara, A.; Gmelin, E. (Physical Review B. 51(1); 1995; 539-546.)

Systematic measurements of the resistivity of the polycrystalline samples of the YBa(2)(Cu(1−x)M(x))(4)O(8) system with M=Fe, Ni are reported. The resistivity behavior depends strongly on the dopant concentration. For the ...
