Distinct Magnetic Phases in Structurally Uniform SrCoO
Z. H. Zhu, F. J. Rueckert, J. I. Budnick +7
Two magnetic phase transitions have been noted for SrCoO for near-stoichiometric oxygen concentrations (small y). Using muon spin rotation and neutron scattering experiment…
Spin-Polarized Quantum Well States on BiFeSe
Michael M. Yee, Z. -H. Zhu, Anjan Soumyanarayanan +8
Low temperature scanning tunneling microscopy is used to image the doped topological insulator BiFeSe. Interstitial Fe defects allow the detection of quasiparticle…
Photoelectron spin-polarization-control in the topological insulator Bi2Se3
Z. -H. Zhu, C. N. Veenstra, S. Zhdanovich +9
We study the manipulation of the photoelectron spin-polarization in BiSe by spin- and angle-resolved photoemission spectroscopy. General rules are established that enable c…
Polarity-driven surface metallicity in SmB
Z. -H. Zhu, A. Nicolaou, G. Levy +7
By a combined angle-resolved photoemission spectroscopy and density functional theory study, we discover that the surface metallicity is polarity-driven in SmB. Two surface sta…
Layer-by-layer entangled spin-orbital texture of the topological surface state in Bi2Se3
Z. -H. Zhu, C. N. Veenstra, G. Levy +7
We study Bi2Se3 by polarization-dependent angle-resolved photoemission spectroscopy (ARPES) and density-functional theory slab calculations. We find that the surface state Dirac fe…
Perovskite BaCrO_{3}: completing a materials system with an anomalous Mott transition
Z. H. Zhu, F. J. Rueckert, J. I. Budnick +4
We have synthesized and characterized laser-deposited film samples of perovskite BaCrO_{3}, a missing member of the perovskite-chromate family. The BaCrO_{3} films have a substanti…
High-pressure structural phase transitions in CuWO4
J. Ruiz-Fuertes, D. Errandonea, R. Lacomba-Perales +9
We study the effects of pressure on the structural, vibrational, and magnetic behavior of cuproscheelite. We performed powder x-ray diffraction and Raman spectroscopy experiments u…
