Abstract

We have measured the magnetic moment of (La_0.9Ba_0.1)₂CuO_4- as a function of temperature and magnetic field and have found the onset of superconductivity at a temperature T {reversed tilde equals} 35 K. From the magnetic field dependencies, we have shown that the sample is a type-II superconductor with ≲ {reversed tilde equals} 11. Specific heat measurements yield a finite electronic specific heat coefficient of ∼6 mJ/mole-K² at 4 K and a Debye temperature of only 330 K, suggesting that a strong electron-phonon interaction may be responsible for the high T in our sample.
