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…
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…
Temperature Dependent Magnetism in Artificial Honeycomb Lattice of Connected Elements
B. Summers, L. Debeer-Schmitt, A. Dahal +4
Artificial magnetic honeycomb lattices are expected to exhibit a broad and tunable range of novel magnetic phenomena that would be difficult to achieve in natural materials, such a…
Metallic Nickel Silicides: Experiments and Theory for NiSi and First Principles Calculations for Other Phases
Ashutosh Dahal, Jagath Gunasekera, Leland Harringer +2
We report detailed experimental investigation of the transport and magnetic properties of orthorhombic NiSi along with first principles studies of this phase and related nickel sil…
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.…
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…
In-plane and out-of-plane correlations in Ho(1-x)YxMnO3
Jagath Gunasekera, Owen P. Vajk, Yuan Wang +2
Strong magnetic-ferroelectric coupling in hexagonal HoMnO3 has been observed previously at spin reorientation temperature between P6'3cm' and the P6'3cm' magnetic phases. In contra…
