Optical properties of LaNiO3 films tuned from compressive to tensile strain
I. Ardizzone, M. Zingl, J. Teyssier +11
Materials with strong electronic correlations host remarkable -- and technologically relevant -- phenomena such as magnetism, superconductivity and metal-insulator transitions. Har…
Unconventional free charge in the correlated semimetal Nd2Ir2O7
K. Wang, B. Xu, C. W. Rischau +9
Nd2Ir2O7 is a correlated semimetal with the pyrochlore structure, in which competing spin-orbit coupling and electron-electron interactions are believed to induce a time-reversal s…
Mott transition and collective charge pinning in electron doped Sr2IrO4
K. Wang, N. Bachar, J. Teyssier +7
We studied the in-plane dynamic and static charge conductivity of electron doped Sr2IrO4 using optical spectroscopy and DC transport measurements. The optical conductivity indicate…
Kubo spins in nano-scale aluminum grains: A muon spin relaxation study
Nimrod Bachar, Aviad Levy, Thomas Prokscha +4
We report muon spin relaxation rate measurements on films composed of aluminum grains having a size of a few nm, with a large energy level splitting of the order of 100 K. The film…
Detailed optical spectroscopy of the hybridization gap and the hidden order transition in high quality URuSi single crystals
N. Bachar, D. Stricker, S. Muleady +4
We present a detailed temperature and frequency dependence of the optical conductivity measured on clean high quality single crystals of URuSi of - and -plane s…
Mott transition in granular aluminum
N. Bachar, S. Lerer, S. Hacohen-Gourgy +4
The presence of free spins in granular Al films is directly demonstrated by SR measurements. A Mott transition is observed by probing the increase of the spin-flip scattering ra…
