Spin dynamics, short-range order and superparamagnetism in superconducting ferromagnet RuSr2Gd1.4Ce0.6Cu2O10-δ
Anuj Kumar, R. P. Tandon, V. P. S. Awana
We report structural, detailed DC and linear/non-linear AC, isothermal and thermoremanent magnetization study of the rutheno-cuprate superconducting ferromagnet RuSr2Gd1.4Ce0.6Cu2O…
Successive spin glass, cluster ferromagnetic, and superparamagnetic transitions in RuSr2Y1.5Ce0.5Cu2O10 complex magneto-superconductor
Anuj Kumar, R. P. Tandon, V. P. S. Awana
We report structural, DC magnetization, detailed linear/non-linear AC susceptibility, (with applied frequency and amplitude) isothermal and thermoremanent magnetization (TRM) behav…
Effect of 3d Metal (Co and Ni) Doping on the Superconductivity of FeSe0.5Te0.5
Anuj Kumar, R. P. Tandon, V. P. S. Awana
We report the effect of 3d metal Cobalt (Co) and Nickel (Ni) doping on the FeTe0.5Se0.5 superconductor with the nominal composition range Fe1-xMxTe0.5Se0.5 (M = Co, Ni and x = 0.00…
Effect of Boron substitution on the superconductivity of non-oxide perovskite MgCNi3
Anuj Kumar, Rajveer Jha, R. P. Tandon +1
We report synthesis, structural and magnetic (DC and AC) properties of Boron substituted MgCNi3 superconductor. A series of polycrystalline bulk samples Mg1.2C1.6-xBxNi3 (x = 0.0,…
Crossing point phenomena (T* = 2.7 K) in specific heat curves of superconducting ferromagnets RuSr2Gd1.4Ce0.6Cu2O10-δ
Anuj Kumar, R. P. Tandon, Jianli Wang +2
Crossing point phenomena are one of the interesting and still puzzling effects in strongly correlated electron systems. We have synthesized RuSr2Gd1.4Ce0.6Cu2O10-δ (GdRu-1222) magn…
Role of interstitial "caged" Fe in the superconductivity of FeTe1/2Se1/2
Anuj Kumar, Anand Pal, R. P. Tandon +1
All samples are synthesized through standard solid state reaction route and are quenched to room temperature systematically at 7000C, 5000C, 3000C and room temperature (RT); named…
