Magnetic order and instability in newly synthesized CoSeAs marcasite
Y. Chen, G. Yumnam, A. Dahal +4
Marcasite class of compounds provide facile platform to explore novel phenomena of fundamental and technological importance, such as unconventional superconductivity or high perfor…
Spin correlation in trigonal EuMnAs
A. Dahal, Yiyao Chen, T. Heitmann +3
The trigonal structure of EuMnAs is an anomaly in the tetragonal 122-type pnictide family. We report detailed investigation of the underlying magnetic correlations in s…
Quantum continuum fluctuations in glassy perovskite Ca(CoRu)O
Yiyao Chen, A. Dahal, J. Rodriguez-Rivera +6
The quantum spin continuum and classical spin freezing, associated with a glassy state, represent two opposite extremes of a correlated electronic material. Here, we report the coe…
Quantum Magnetic Properties in Perovskite with Anderson Localized Artificial Spin-1/2
J. Gunasekera, A. Dahal, Y. Chen +7
Quantum magnetic properties in a geometrically frustrated lattice of spin-1/2 magnet, such as quantum spin liquid or solid and the associated spin fractionalization, are considered…
Electronic nature of the lock-in magnetic transition in CeXAl4Si2
J. Gunasekera, L. Harriger, A. Dahal +6
We have investigated the underlying magnetism in newly discovered single crystal Kondo lattices CeXAl4Si2, where X = Rh, Ir. We show that the compound undergoes an incommensurate-t…
Magnetic fluctuations driven insulator-to-metal transition in Ca(IrRu)O
J. Gunasekera, L. Harriger, A. Dahal +3
Magnetic fluctuations in transition metal oxides are a subject of intensive research because of the key role they are expected to play in the transition from the Mott insulator to…
Quasi-local critical nature of cooperative paramagnetic fluctuations in CaRuO metal
J. Gunasekera, L. Harriger, T. Heitmann +2
We report new observation of cooperative paramagnetic fluctuations of Ru spins that coexist with the non-Fermi liquid state in CaRuO perovskite below T 22 K.…
