The crystal structure, superconducting properties and oxygen stoichiometry of room temperature chemically oxidized La2\_~grxCuO4+y (x= 0.05, 0.09) have been studied by means of powder neutron diffraction, magnetic susceptibility and thermogravimetric analysis. The presence in these materials of inte
We present measuxements of the low temperature specific heat (0.09K< T < 1.5K) of seven samples of the La2\_~Sr~CuO4 system (0.05< z <0.27). All the data were found to fit the expression, C = A(x)T -2 +a(x)T'~(~)+ fl(z)T 3. The coefficient of the nuclear specific heat contribution A(z) was found to
