Successive magnetic transitions and multiferroicity in layered honeycomb BiCrTeO
Arkadeb Pal, P. H. Lee, J. Khatua +12
Low-dimensional magnetic systems based on honeycomb lattices provide a promising platform for exploring exotic quantum phenomena that emerge from the intricate interplay of competi…
Possible realization of a randomness-driven quantum disordered state in an S = 1/2 antiferromagnet Sr3CuTa2O9
B. Sana, M. Barik, S. Lee +9
Collective behavior of spins, frustration-induced strong quantum fluctuations, and subtle interplay between competing degrees of freedom in quantum materials can lead to correlated…
Magnetic properties of a spin-orbit entangled Jeff = 1/2 honeycomb lattice
J. Khatua, Q. P. Ding, M. S. Ramachandra Rao +4
The interplay between spin-orbit coupling, anisotropic magnetic interaction, frustration-induced quantum fluctuations and spin correlations can lead to novel quantum states with ex…
Anomalous electronic Raman scattering in Na_xCoO_2 H_2O
P. Lemmens, K. Y. Choi, V. Gnezdilov +5
Raman scattering experiments on Na_{x}CoO_2 yH_2O single crystals show a broad electronic continuum with a pronounced peak around 100 cm-1 and a cutoff at approximately 560 cm-1ove…
Spin gap formation in the quantum spin systems TiOX, X=Cl and Br
P. Lemmens, K. Y. Choi, R. Valenti +4
In the layered quantum spin systems TiOCl and TiOBr the magnetic susceptibility shows a very weak temperature dependence at high temperatures and transition-induced phenomena at lo…
Effect of Na content and hydration on the excitation spectrum of the cobaltite Na_xCoO_2 yH_2O
P. Lemmens, V. Gnezdilov, N. N. Kovaleva +8
We report on a Raman scattering study on the superconducting cobaltite as function of Na content and hydration (x1/3, 3/4 and y0, 2/3, 4/3)…
