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…
Effect of PVA doping on flux pinning in Bulk MgB2
Arpita Vajpayee, V. P. S. Awana, S. Balamurugan +3
The synthesis and characterization of PVA (Poly Vinyl Acetate) doped bulk MgB2 superconductor is reported here. PVA is used as a Carbon source. PVA doping effects made two distingu…
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…
Inter comparison of the magneto transport of La2/3Ca1/3MnO3: Ag/In polycrystalline composites
Rahul Tripathi, V. P. S. Awana, S. Balamurugan +4
In this article, we report the synthesis, magneto transport features, and magnetization of polycrystalline La2/3Ca1/3MnO3:Agx/Inx composites with x = 0, 0.1, 0.2, 0.3 and 0.4. In c…
