Room-Temperature Valence Transition in a Strain-Tuned Perovskite Oxide
Vipul Chaturvedi, Supriya Ghosh, Dominique Gautreau +17
Cobalt oxides have long been understood to display intriguing phenomena known as spin-state crossovers, where the cobalt ion spin changes vs. temperature, pressure, etc. A very dif…
Uniaxial strain control of bulk ferromagnetism in rare-earth titanates
Ana Najev, Sajna Hameed, Dominique M. Gautreau +7
The perovskite rare-earth titanates are model Mott insulators with magnetic ground states that are very sensitive to structural distortions. These distortions couple strongly to th…
Strain-tunable metamagnetic critical endpoint in Mott insulating rare-earth titanates
Zhentao Wang, Dominique Gautreau, Turan Birol +1
Rare-earth titanates are Mott insulators whose magnetic ground state -- antiferromagnetic (AFM) or ferromagnetic (FM) -- can be tuned by the radius of the rare-earth element. Here,…
Two-component electronic phase separation in the doped Mott insulator YCaTiO
S. Hameed, J. Joe, D. M. Gautreau +3
One of the major puzzles in condensed matter physics has been the observation of a Mott-insulating state away from half-filling. The filling-controlled Mott insulator-metal transit…
First-principles characterization of the magnetic properties of Cu(OH)Br
Dominique M. Gautreau, Amartyajyoti Saha, Turan Birol
Low dimensional spin-1/2 transition metal oxides and oxyhalides continue to be at the forefront of research investigating nonclassical phases such as quantum spin liquids. In this…
