Title (up) Magnetic ordering in dilute GdxEu1−xBa2Cu3O7−δ superconductors Type Journal Article
Year 1988 Publication Physica C: Superconductivity Abbreviated Journal Physica C
Volume 153 Issue Pages 188-189
Keywords
Abstract We have measured the specific heat of GdxEu1−xBa2Cu3O7−δ (0 ≤ × ≤ 1). The data show a λ-type anomaly at high concentrations and a broad Schottky type anomaly at intermediate and low concentrations. We compare this behavior with theoretical predictions for a 2-dimensional Ising system.

Title (up) Magnetization and specific heat of La doped Sr2FeMoO6 Type Journal Article
Year 2004 Publication JOURNAL OF MAGNETISM AND MAGNETIC MATERIALS Abbreviated Journal J. Magn. Magn. Mater.
Volume 272 Issue Pages 857-858
Keywords
Abstract We present high-temperature magnetization and low-temperature specific heat measurements performed on the electron doped double perovskite Sr1.7La0.3FeMoO6. We have obtained the electronic contribution to C-p, gamma = 11.5(5) mJ/mol K-2. The electronic susceptibility, derived from the magnetic measurements in the paramagnetic regime (T > T-c = 390K), was chi(e)(0) =(4.9 +/- 1.5) x 10(-4) emu/mol. Anti ferromagnetic coupling between localized and itinerant moments was inferred from the data, with a coupling constant lambda = -(475 +/- 50)mol/emu, that results in a ferromagnetic-like Curie-Weiss susceptibility with Theta = 390(5) K. These results are compared with those obtained for the undoped material. (C) 2003 Published by Elsevier B.V.

Title (up) Specific heat, magnetic susceptibility and electrical resistivity measurements on LaNiO3 Type Journal Article
Year 1993 Publication Journal of Alloys and Compounds Abbreviated Journal J. Alloys Compd.
Volume 191 Issue 2 Pages 287–289
Keywords
Abstract Measurements of specific heat, magnetic susceptibility and electrical resistivity on LaNiO3 are reported. No evidence of magnetic ordering or metal-insulator transitions is found. From the measured electronic specific heat parameter γ and the Pauli susceptibility χP, a Stoner enhancement parameter is derived. Comparison with band structure calculations performed by other workers is also made.
