Characterizing oxygen atoms in perovskite and pyrochlore oxides using ADF-STEM at a resolution of a few tens of picometers
Ali Mostaed, Brant Walkley, Monica Ciomaga Hatnean +5
We present an aberration corrected scanning transmission electron microscopy (ac-STEM) analysis of the perovskite (LaFeO3) and pyrochlore (Yb2Ti2O7 and Pr2Zr2O7) oxides and demonst…
Optical floating zone crystal growth of rare-earth disilicates, SiO ( Er, Ho, and Tm)
Monica Ciomaga Hatnean, Oleg A. Petrenko, Martin R. Lees +2
The wealth of structural phases seen in the rare-earth disilicate compounds promises an equally rich range of interesting magnetic properties. We report on the crystal growth by th…
Definitive Surface Magnetotransport Study of SmB
Yun Suk Eo, Steven Wolgast, Alexa Rakoski +11
After the theoretical prediction that SmB is a topological Kondo insulator, there has been an explosion of studies on the SmB surface. However, there is not yet an agreemen…
Fermi surface in the absence of a Fermi liquid in the Kondo insulator SmB
M. Hartstein, W. H. Toews, Y. -T. Hsu +23
The search for a Fermi surface in the absence of a conventional Fermi liquid has thus far yielded very few potential candidates. Among promising materials are spin-frustrated Mott…
Signatures of the Kondo effect in VSe2
Sourabh Barua, M. Ciomaga Hatnean, M. R. Lees +1
VSe2 is a transition metal dichaclogenide which has a charge-density wave transition that has been well studied. We report on a low-temperature upturn in the resistivity and, at te…
Disorder and Quantum spin ice
N. Martin, P. Bonville, E. Lhotel +7
We report on diffuse neutron scattering experiments providing evidence for the presence of random strains in the quantum spin ice candidate Pr2Zr2O7. Since Pr is a non-Kramers ion,…
