“CLBLCO” is a family of 1-2-3 superconductors, represented by the chemical formula (Ca x La 1− x )(Ba c − x La 2− c + x )Cu 3 O y . By annealing in oxygen at various pressures, up to 4300 bar, at a temperature of 300°C and above, we have p

Measurements of the resistivity of Pr1−zCazBa2Cu3O7−δ (for z ≲ 1 2 ) as a function of temperature show that below room temperature, thermally activated hopping is the dominant conduction mechanism in this material; an apparent crossover is see

It was apparent in this workshop that the scientific community has not yet reached a consensus concerning a microscopic theory for the high-T c cuprates. The BCS theory assumes a model of free electrons plus a pairing interaction; it contains the ess

Much recent research has been devoted to the PrxYl-xBa2Cu3O7-δ system (“PYBCO”), for a wide range of values of x and δ, in both its normal (“n-PYBCO”) and superconducting (“s-PYBCO”) states. The reason for the interest in this system is

We investigated the Pr x Y 1- x Ba 2 Cu 3 O 7-δ system, system, varying both the Pr and oxygen content and measured the resistivity as function of composition and temperature. Including literature data on T N , a phase diagram was constructed, which

A theory of the coexistence of superconductivity and antiferromagnetism is presented. We study the role of the ''diagonal'' exchange coupling between magnetic ions and conduction electrons, using Eliashberg's formalism. This coupling generates a spat

A statistical theory of neutral kaon decay is presented, in which the violation of combined CP parity arises through non-equilibrium interaction with a heat bath, and not through a microscopic CP-violating term in the Hamiltonian. The theory is set u
