Impact of rare earth magnetic moment on ordering of Ru in Sr2RuREO6 (RE = Gd and Eu)
V. P. S. Awana, Rahul Tripaathi, V. K. Sharma +3
We report synthesis and magnetization of Sr2RuREO6 (RE/Ru-211O6) with RE = Gd and Eu. Both Gd,Eu/Ru-211O6 are formed in distorted perovskite-type single phase with monoclinic P21/n…
Magneto Transport of high TCR (temperature coefficient of resistance) La2/3Ca1/3MnO3: Ag Polycrystalline Composites
V. P. S. Awana, Rahul Tripathi, S. Balamurugan +2
We report the synthesis, (micro)structural, magneto-transport and magnetization of polycrystalline La2/3Ca1/3MnO3:Agx composites with x = 0.0, 0.1, 0.2, 0.3 and 0.4. The temperatur…
Unconventional Superconductivity Induced by Quantum Critical Fluctuations in Hydrate Cobaltate Na(HO)CoO HO -- Relationship between Magnetic Fluctuations and the Superconductivity Revealed by a Co Nuclear Quadrupole Resonance --
Y. Ihara, H. Takeya, K. Ishida +7
Co nuclear-quadrupole-resonance (NQR) measurements were performed on various bilayered hydrate cobaltate Na_x(H_3O)_zCoO_2\cdot yH_2O with different values of the superconducting a…
High pressure high temperature (HPHT) synthesis and magnetism of MSr2Y1.5Ce0.5Cu2O10 compounds with M = Ru, Mn, and Cr
V. P. S. Awana, S. Balamurugan, H. Kishan +1
The M-1222 compounds are synthesized in near single phase form. These compounds crystallise in I4/mmm Tetragonal structure. None of the studied compound is superconducting but they…
Physical property characterization of Fe-tube encapsulated and vacuum annealed bulk MgB2
V. P. S. Awana, Rajeev Rawat, Anurag Gupta +6
We report phase formation, and detailed study of magnetization and resistivity under magnetic field of MgB2 polycrystalline bulk samples prepared by Fe-tube encapsulated and vacuum…
Anomalous lattice expansion of RuSr2Eu1.5Ce0.5Cu2O10(Ru-1222) magneto superconductor: A low temperature X-ray diffraction study
V. P. S. Awana, Rajeev Ranjan, Rajeev Rawat +8
This is the first report of the observation of the onset of excess volume and also of the strain along the a-axis near the magnetic ordering temperature in Ru-1222 superconductor,…
