Physics and Materials Science of High Temperature Superconductors, II represents the results of a fruitful dialogue between physicists and materials scientists which took place under the auspices of a NATO Advanced Study Institute in Porto Carras, Greece, between 18 and 31 August, 1991. It builds on and carries forward the success of NATO ASI 181 published in 1990. The theoretical side of the discussions reveal the basic premise of the phenomenological and Ginzburg-Landau theories of superconductivity, the implications of short coherence length, long penetration depth, the melting of flux lattices, and other matters, while the materials science includes discussions of microstructures, local inhomogeneities, deviations from ideal chemistry, the effects of systematic errors in materials preparation, the definition of imperfections, and the utilization of common materials analysis techniques. The reader will be made aware of the potential significance of Angstrom scale structural and chemical details, and the need to consider basic theoretical concepts when designing procedures to process viable, solid conductors, specifically the effects of oxygen stoichiometry and deviations from it, as well as the microstructural demands on pinning in the light of very short coherence lengths.Now we calculate the constant C(qm) using the experimental value of Tc=105K and the calculated value of an5 for L=2 in Ap Once ... Outside this range, our equations are not valid and we will not have superconducitvity. ... 105 (exact) 3 0.142 108 4 0.144 110 For numerical computation we have chosen qm-kFV2= 0.224A-1 which gives us values of Go, A, ... results for the low frequency behavior of the loss function Im(-1/8(a)) due to excitation of plasmons in the layered compounds andanbsp;...
