Triplet-Pair Spin Signatures from Macroscopically Aligned Heteroacenes in an Oriented Single Crystal
Brandon K. Rugg, Kori E. Smyser, Brian Fluegel +6
The photo-driven process of singlet fission generates coupled triplet pairs (TT) with fundamentally intriguing and potentially useful properties. The quintet 5TT0 sublevel is parti…
Magnetization reversal and negative volume thermal expansion in Fe doped Ca2RuO4
S. J. Yuan, T. F. Qi, J. Terzic +9
We report physical and structural properties of single-crystal Ca2Ru1-xFexO4 (0<x<0.20) as functions of temperature, magnetic field and pressure. Ca2RuO4 is a structurally-driven M…
Magnetic and Orbital Orders Coupled to Negative Thermal Expansion in Mott Insulators, Ca2Ru1-xMxO4 (M = Mn and Fe)
T. F. Qi, O. B. Korneta, S. Parkin +2
Ca2RuO4 is a structurally-driven Mott insulator with a metal-insulator transition at TMI = 357K, followed by a well-separated antiferromagnetic order at TN = 110 K. Slightly substi…
Giant Magnetoelectric Effect in Antiferromagnetic BaMnO3-δand Its Derivatives
O. B. Korneta, T. F. Qi, M. Ge +4
Hexagonal perovskite 15R-BaMnO2.99 with a ratio of cubic to hexagonal layers of 1/5 in the unit cell is an antiferromagnetic insulator that orders at a Néel temperature TN = 220 K.…
Ca2Ru1-xCrxO4 (0 < x < 0.13): Negative volume thermal expansion via orbital and magnetic orders
T. F. Qi, O. B. Korneta, S. Parkin +3
Ca2RuO4 undergoes a metal-insulator transition at TMI = 357 K, followed by a well-separated transition to antiferromagnetic order at TN = 110 K. Dilute Cr doping for Ru reduces the…
Electron-Doped Sr2IrO4-delta (0 <= delta <= 0.04): Evolution of a Disordered Jeff = 1/2 Mott Insulator into an Exotic Metallic State
O. B. Korneta, Tongfei Qi, S. Chikara +3
Stoichiometric Sr2IrO4 is a ferromagnetic Jeff = 1/2 Mott insulator driven by strong spin-orbit coupling. Introduction of very dilute oxygen vacancies into single-crystal Sr2IrO4-d…
