The superconductivity mechanism in Nd-1111 iron-based superconductor doped by calcium
F. Shahbaz Tehrani, V. Daadmehr
We described the effect of nonmagnetic impurity on the superconductivity behavior of the NdFeAsO0.8F0.2 iron-based superconductor. The resistivity measurement showed that the super…
The empirical aspects of Eliashberg formalism for the superconducting mechanism in Iron-based superconductors
F. Shahbaz Tehrani, V. Daadmehr
We have investigated experimentally how properties of NdFeAsO0.8F0.2 superconductor affected due to the substitution of the Ca2+/Nd3+ doping. Based on the XRD data refinement, vari…
The calcium doping effects on the structural and electrical properties of NdFeAsO0.8F0.2
F. Shahbaz Tehrani, V. Daadmehr
We have investigated experimentally how properties of NdFeAsO0.8F0.2 superconductor affected due to the substitution of the calcium by the neodymium. We have synthesized polycrysta…
Y358 against Y123 structural phase in a Y-based superconductor
S. Gholipour, V. Daadmehr, A. T. Rezakhani +3
We report an experiment in which two distinct superconducting phase YBa2Cu3O7 (Y123) and Y3Ba5Cu8O18 (Y358) coexisted. This enabled us to characterize the recently introduced Y358…
Catalytic effect of the spinel ferrite nanocrystals on the growth of carbon nanotubes
R. Hosseini Akbarnejad, V. Daadmehr, F. Shahbaz Tehrani +2
We prepared three ferrite nanocatalysts: (i) copper ferrite (CuFe2O4), (ii) ferrite where cobalt was substituted by nickel (NixCo1-xFe2O4, with x= 0, 0.2, 0.4, 0.6), and (iii) ferr…
