Comparison of the superconducting critical transition temperature of LaBaCaCu3O7-d and NdBaCaCu3O7-d
V. P. S. Awana, M. A. Ansari, Rashmi Nigam +3
LaBaCaCu3O7 (La:1113) and NdBaCaCu3O7 (Nd:1113) compounds are synthesized by solid state reaction route. Both compounds crystallize in tetragonal structure. Four probe resistivity…
Effect of Sr substitution on the stability of CuO chains in oxygen and nitrogen annealed YBa2-xSrxCu3O(x = 0.0, 0.50, 1.0) superconducting system
M. A. Ansari, V. P. S. Awana, Anurag Gupta +2
Samples of YBa2-xSrxCu3O7-d (x = 0.0, 0.50, 1.0) series were synthesized by solid-state reaction and first annealed in flowing O2 gas. All samples crystallized in orthorhombic stru…
Spin Glass Behavior in the Ru-1222 and Ru-1212 rutheno-cuprate families: a comparative study
C. A. Cardoso, F. M. Araujo-Moreira, V. P. S. Awana +3
Strong evidences of a spin glass phase on polycrystalline RuSr2Ln1.5Ce0.5Cu2O10-x (LnRu-1222, Ln = Y, Ho and Dy) is provided by ac susceptibility and dc magnetization measurements.…
Magnetism and Superconductivity in RuM1.5Ce0.5Sr2Cu2O10 (M=Eu and Y)
I. Felner, E. Galstyan, V. P. S. Awana +1
RuY1.5Ce0.5Sr2Cu2O10, is not superconducting (SC) and orders magnetically at TM =152 K. The Ru moment at 5K is 0.75 mB. Ferromagnetic hysteresis loops are observed below Tirr= 100…
