Strong coupling of lattice and orbital excitations in quantum magnet CaCrO: Anomalous temperature dependence of Raman phonons
Srishti Pal, Arnab Seth, Anzar Ali +4
We report low-temperature Raman signatures of the Heisenberg quantum magnet CaCrO, showing clear anomalies in phonon mode frequencies and linewidths below 1…
Pressure tuning of structure, magnetic frustration and carrier conduction in Kitaev spin liquid candidate CuIrO: X-ray, Raman, magnetic susceptibility, resistivity and first-principles analysis
Srishti Pal, Pallavi Malavi, Arijit Sinha +8
The layered honeycomb lattice iridate CuIrO is the closest realization of the Kitaev quantum spin liquid, primarily due to the enhanced interlayer separation and nearly ide…
Raman fingerprints of fractionalized Majorana excitations in honeycomb iridate AgLiIrO
Srishti Pal, Vinod Kumar, Debendra Prasad Panda +4
We report low-temperature (down to 5 K) Raman signatures of the recently discovered intercalated honeycomb magnet AgLiIrO, a putative Kitaev quantum spin liquid (…
Role of spin-phonon and electron-phonon interactions in phonon renormalization of (EuBi)IrO across the metal-insulator phase transition: Temperature-dependent Raman and X-ray studies
Anoop Thomas, Prachi Telang, Kshiti Mishra +5
We report temperature-dependent Raman scattering and X-ray diffraction studies of pyrochlore iridates, (EuBi)IrO, for x=0, 0.02, 0.035, 0.05 and 0.1. The te…
Probing signatures of fractionalization in candidate quantum spin liquid Cu2IrO3 via anomalous Raman scattering
Srishti Pal, Arnab Seth, Piyush Sakrikar +5
Long-range entanglement in quantum spin liquids (QSLs) lead to novel low energy excitations with fractionalised quantum numbers and (in 2D) statistics. Experimental detection and m…
Spin liquid like Raman signatures in hyperkagome iridate NaIrO
Satyendra Nath Gupta, P. V. Sriluckshmy, Ashiwini Balodhi +5
Combining Raman scattering measurements with mean field calculations of the Raman response we show that Kitaev-like magnetic exchange is dominant in the hyperkagome iridate NaI…
Raman Signatures of Strong Kitaev Exchange Correlations in (NaLi)IrO : Experiments and Theory
Satyendra Nath Gupta, P. V. Sriluckshmy, Kavita Mehlawat +7
Inelastic light scattering studies on single crystals of (NaLi)IrO ( and ) show a polarization independent broad band at ~2750 cm$^{-1…
