Quantum magnetic properties and metal-to-insulator transition in chemically doped calcium ruthenate perovskite
Deepak K. Singh, Arthur Ernst, Vitalii Dugaev +2
Ruthenates provide comprehensive platform to study a plethora of novel properties, such as quantum magnetism, superconductivity and magnetic fluctuation mediated metal-insulator tr…
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…
Mott insulator-to-metal transition in yttrium-doped CaIrO3
J. Gunasekera, Y. Chen, J. W. Kremenak +2
We report on the study of insulator-to-metal transition in post-perovskite compound CaIrO3. It is discovered that a gradual chemical substitution of calcium by yttrium leads to the…
