Negative thermal expansion, lattice dynamics, and complex magnetism in TbFeO
Shubham Farswan, Reshma Kumawat, Dipankar Sarkar +4
We report a temperature-dependent investigation of orthoferrite TbFeO using x-ray diffraction, DC magnetization, and Raman scattering, complemented by room-temperature x-ray ph…
Non-adiabatic phonon renormalization in metallic versus insulating rutile oxides
Reshma Kumawat, Shubham Farswan, Simranjeet Kaur +1
We present a comparative Raman scattering study of metallic rutile oxides (RuO and IrO) and insulating rutiles (TiO and SnO). Temperature-dependent Raman spectra re…
Anomalous lattice anharmonicity and spin-lattice coupling in spin orbit coupled halide K2IrBr6
S. Bhatia, A. Ahmad, M. Zeeshan +5
The interplay between lattice distortions, magnetism, and spin-orbit coupling in 5d transition-metal halides offers a fertile platform for exploring correlated spin-lattice dynamic…
Bulk-like structural, magnetic and optical properties of (111)- and (001)-NiO thin films
S. Kaur, Smriti Bhatia, Pooja +4
We have grown (111)- and (001)-oriented NiO thin films on (0001)-Sapphire and (001)-MgO substrates using pulsed laser deposition (PLD), respectively. DC magnetic susceptibility mea…
Potential of Raman scattering in probing magnetic excitations and their coupling to lattice dynamics
Reshma Kumawat, Shubham Farswan, Simranjeet Kaur +2
Raman scattering is an excellent method for simultaneously determining the dynamics of lattice, spin, and charge degrees of freedom. Furthermore, polarization selection rules in Ra…
Strange semimetal dynamics in SrIrO
Kaushik Sen, Dirk Fuchs, Rolf Heid +4
The interplay of electronic correlations, multi-orbital excitations, and strong spin-orbit coupling is a fertile ground for new states of matter in quantum materials. Here, we repo…
