چکیده
The well known phenomenological theory of F. and H. London leads to rather severe restrictions for the electronic wave functions which might possibly account for the phenomenon of superconductivity. Yet all attempts to construct such wave functions according to the principle of quantum mechanics have been so far unsuccessful. This failure seems to stem from the use of one-electron functions for a problem for which the electronic interaction is of great importance. It was generally assumed that the many electron wave functions are too difficult to handle. Actually, the Bloch-Slater theory of ferromagnetism required the use of many electron functions, but these were not associated with any current and thus were not appropriate for a theory of either normalor super-con-

Hopping Conductivity in Single Crystals (Cd0.6Zn0.32Mn0.08)3As2 (RESEARCH NOTE)
The growth processes of Tetragonal single crystals of solid solution (Cd0.6Zn0.32Mn0.08)3As2, space group P42/nmc, has been synthesized by Bridgman method. Conductivity and magnetoresistance of (Cd0.6Zn0.32Mn0.08)3As2 were measured in the range 1.6K to 300K and in magnetic field up to 25 T. Crossover from Mott variable-range-hopping conductivity mechanism close to helium temperatures. In this w...
متن کاملKinetic Study of the Linkage Isomers in [Co(NH3)5ONO]X2 (X=Cl¯, Br¯, I¯) in the Solid State in KBr Discs
The nitrite ® nitro isomerization in nitritopentaamine cobalt (III) halides has been known. In this paper, the effect of the size of the counter ions (noncoordinated groups) on the rate of isomerization in nitritopentaamine cobalt (III) halides, is reported. The rate of isomerization is decreased by increasing the size of the counter ions. This decrease is explained on the...

Nanostructured Ni1-xLnxSb2O6 (Ln = Eu, Gd, Ho and Yb) powders were synthesized via stoichiometric 1:2 Ni:Sb molar ratio by solid state reaction at 800 ºC for 8 h using Ni(NO3)2, Sb2O3, Eu2O3, Gd2O3 and Ho2O3 raw materials. The synthesized materials were characterized by X-ray diffraction (XRD) technique. Structural analyses were done by FullProf program employing profile matching with constant ...
