Carrier Transport in Magnesium Diboride: Role of Nano-inclusions
A. M. Awasthi, S. Bhardwaj, V. P. S. Awana +3
Anisotropic-gap and two-band effects smear out the superconducting transition (Tc) in literature reported thermal conductivity of MgB2, where large electronic contributions also su…
Anomalous thermoelectric power of Mg1-xAlxB2 system with x = 0.0 to 1.0
Monika Mudgel, V. P. S. Awana, R. Lal +5
Thermoelectric power, S(T) of the Mg1-xAlxB2 system has been measured for x = 0.0, 0.1, 0.2, 0.4, 0.6, 0.8 and 1.0. XRD, resistivity and magnetization measurements are also present…
High Field Performance of Nano-Diamond Doped MgB2 Superconductor
Arpita Vajpayee, V. P. S. Awana*, H. Kishan +3
Polycrystalline MgB2-nDx (x= 0 to 0.1) samples are synthesized by solid-state route with ingredients of Mg, B and n-Diamond. The results from magneto-transport and magnetization of…
Role of Carbon in Enhancing the Performance of MgB2 superconductor
V. P. S. Awana, Arpita Vajpayee, Monika Mudgel +6
The enhancement of the critical current density (Jc(H)) of carbon and nano-SiC doped MgB2 is presented and compared. The upper critical field (Hc2) being determined from resistivit…
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,…
