Disorder induced power-law gaps in an insulator-metal Mott transition
Zhenyu Wang, Yoshinori Okada, Jared O'Neal +11
A correlated material in the vicinity of an insulator-metal transition (IMT) exhibits rich phenomenology and variety of interesting phases. A common avenue to induce IMTs in Mott i…
Fermi Arcs vs. Fermi Pockets in Electron-doped Perovskite Iridates
Junfeng He, H. Hafiz, Thomas R. Mion +11
We report on an angle resolved photoemission (ARPES) study of bulk electron-doped perovskite iridate, (Sr1-xLax)3Ir2O7. Fermi surface pockets are observed with a total electron cou…
Spectroscopic evidence for negative electronic compressibility in a quasi-three-dimensional spin-orbit correlated metal
Junfeng He, T. Hogan, Thomas R. Mion +20
Negative compressibility is a sign of thermodynamic instability of open or non-equilibrium systems. In quantum materials consisting of multiple mutually coupled subsystems, the com…
Effect of carrier concentration on magnetism and magnetic order in the pyrochlore iridates
M. J. Graf, S. M. Disseler, Chetan Dhital +9
We present resistivity, magnetization, and zero field muon spin relaxation (SR) data for the pyrochlore iridate materials NdCaIrO (, and $…
Spin correlated electronic state on the surface of a spin-orbit Mott system (Layered Iridates)
Chang Liu, Su-Yang Xu, Nasser Alidoust +13
Novel phases of two dimensional electron systems resulting from new surface or interface modified electronic structures have generated significant interest in material science. We…
Carrier localization and electronic phase separation in a doped spin-orbit driven Mott phase in Sr3(Ir1-xRux)2O7
Chetan Dhital, Tom Hogan, Wenwen Zhou +13
Interest in many strongly spin-orbit coupled 5d-transition metal oxide insulators stems from mapping their electronic structures to a J=1/2 Mott phase. One of the hopes is to estab…
Magnetization and Hall effect studies on the pyrochlore iridate Nd2Ir2O7
S. M. Disseler, S. R. Giblin, Chetan Dhital +3
We present magnetization and Hall effect measurements on the pyrochlore iridate Nd2Ir2O7. Previous muon spin rotation measurements have shown that the system undergoes an unusual t…

Neutron scattering study of magnetic phase separation in nanocrystalline LaCaMnO
Chetan Dhital, Clarina de la Cruz, C. Opeil +5
We demonstrate that magnetic phase separation and competing spin order in the colossal magnetoresistive (CMR) manganites can be directly explored via tuning strain in bulk samples…
