Frustration induced inversion of magnetocaloric effect and enhanced cooling power in substituted Pyrochlore Iridates
Vinod Kumar Dwivedi, Prabhat Mandal, Soumik Mukhopadhyay
We investigate the effect of partial replacement of extended 5d Ir4+ sites by localized 3d Cr3+ moments on the magnetocaloric properties of Y2Ir2O7 (YIO) pyrochlore iridates. We fi…
Non-Fermi liquid regime in metallic pyrochlore iridates: Quantum Griffiths singularities
Bikash Ghosh, Vinod Kumar Dwivedi, Soumik Mukhopadhyay
We investigate the interplay of Kondo and RKKY coupling in presence of disorder by chemically substituting local moment Cr^{3+} at the Ir sublattice in the metallic Pr_{2}Ir_{2}O_{…
Influence of electronic structure parameters on the electrical transport and magnetic properties of pyrochlore iridates
Vinod Kumar Dwivedi, Soumik Mukhopadhyay
We report the systematic study of structural, magnetic and electrical transport properties of (x = 0.0, 0.1, 0.2, 0.3) pyrochlore iridates. The chemical doping…
Suppression of long range magnetic ordering and electrical conduction in YBiIrO thin film
Vinod Kumar Dwivedi, Soumik Mukhopadhyay
We find that the long-range magnetic ordering is absent and electrical conduction suppressed in YBiIrO/YSZ(100) thin film prepared by pulsed laser depositio…
Coexistence of high electrical conductivity and weak ferromagnetism in Cr doped YIrO pyrochlore iridate
Vinod Kumar Dwivedi, Soumik Mukhopadhyay
We report the structural, magnetic and electrical transport properties of YIrCrO pyrochlore iridates. The chemical doping leads to order of magnitude enhancemen…
