Structural distortion below the Néel temperature in spinel GeCoO
Phillip T. Barton, Moureen C. Kemei, Michael W. Gaultois +5
A structural phase transition from cubic to tetragonal 4/ symmetry with 1 is observed at = 16 K in spinel GeCoO below the Néel…
First-principles study of band alignments in the p-type hosts BaM2X2 (M = Cu, Ag; X = S, Se)
Aditi Krishnapriyan, Phillip T. Barton, Maosheng Miao +1
The electronic structures of four semiconductor compounds BaCu2S2, BaCu2Se2, BaAg2S2, and BaAg2Se2 are studied by density functional theory using both semi-local and hybrid functio…
Magnetocapacitance as a sensitive probe of magnetostructural changes in NiCrO
Taylor D. Sparks, Moureen C. Kemei, Phillip T. Barton +3
The spinel NiCrO is characterized using dielectric and high magnetic field measurements. The trends in the magnetodielectric response fall into three clear temperature regi…
Magnetostructural transition, metamagnetism, and magnetic phase coexistence in Co10Ge3O16
Phillip T. Barton, Ram Seshadri, Anna Llobet +1
Co10Ge3O16 crystallizes in an intergrowth structure featuring alternating layers of spinel and rock salt. Variable-temperature powder synchrotron X-ray and neutron diffraction, mag…
Crystal structures of spin-Jahn-Teller ordered MgCr_2O_4 and ZnCr_2O_4
Moureen C. Kemei, Phillip T. Barton, Stephanie L. Moffitt +5
Magnetic ordering in the geometrically frustrated magnetic oxide spinels MgCr_2O_4 and ZnCr_2O_4 is accompanied by a structural change that helps relieve the frustration. Analysis…
Structural disorder, magnetism, and electrical and thermoelectric properties of pyrochlore Nd2Ru2O7
Michael W. Gaultois, Phillip T. Barton, Christina S. Birkel +4
Polycrystalline Nd2Ru2O7 samples have been prepared and examined using a combination of structural, magnetic, and electrical and thermal transport studies. Analysis of synchrotron…
Structural and magnetic characterization of the complete delafossite solid solution (CuAlO2){1-x}(CuCrO2){x}
Phillip T. Barton, Ram Seshadri, Andrea Knöller +1
We have prepared the complete delafossite solid solution series between diamagnetic CuAlO2 and the t2g^3 frustrated antiferromagnet CuCrO2. The evolution with composition x in CuAl…
Electrical and magnetic properties of the complete solid solution series between SrRuO3 and LaRhO3: Filling t2g versus tilting
Phillip T. Barton, Ram Seshadri, Matthew J. Rosseinsky
A complete solid solution series between the t2g^4 perovskite ferromagnet SrRuO3 and the diamagnetic t2g^6 perovskite LaRhO3 has been prepared. The evolution with composition x in…
