Identification of Griffiths-like phase and its evolution in Cr substituted pyrochlore iridates
Vinod Kumar Dwivedi
We report the Griffiths phase (GP)-like state along with cluster-glass-like state in geometrically frustrated antiferromagnetic substituted pyrochlore iridates. T…
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_{…
Colossal enhancement of electrical conductivity in Y2Ir2O7 nanoparticles
Vinod Kumar Dwivedi, Abhishek Juyal, Soumik Mukhopadhyay
We present a comparative study of the magnetic and electrical properties of polycrystalline and nanocrystalline Y2Ir2O7, the latter prepared using a new chemical route. We find tha…
