Suppression of multiferroic order in hexagonal YMn1-xInxO3 ceramics

A. Dixit, Andrew E. Smith, M. A. Subramanian +1

We have investigated the effects of substituting In for Mn on the antiferromagnetic phase transition in YMnO3 using magnetic, dielectric, and specific heat measurements. We prepare…

Magnetically tunable dielectric materials

G. Lawes, T. Kimura, C. M. Varma +3

The coupling between localized spins and phonons can lead to shifts in the dielectric constant of insulating materials at magnetic ordering transitions. Studies on isostructural Se…

First principles studies of SnTiO3 perovskite as a potential ferroelectric material

S. F. Matar, M. A. Subramanian, I. Baraille

In the context of the search for environment-respectful, lead- and bismuth- free chemical compounds for devices such as actuators, SnTiO3 (ST) is investigated from first principles…

An experimental and computational investigation of structure and magnetism in pyrite CoFeS: Chemical bonding and half-metallicity

K. Ramesha, Ram Seshadri, Claude Ederer +2

Bulk samples of the pyrite chalcogenide solid solutions CoFeS 0 <= x <= 0.5, have been prepared and their crystal structures and magnetic properties studied by X-ra…

Valence-electron transfer and a metal-insulator transition in a strongly correlated perovskite oxide

A. P. Ramirez, G. Lawes, D. Li +1

We present transport and thermal data for the quadruple-perovskites MCu3(Ti1-xRux)4O12 where 0 < x < 1. A metal-insulator transition (MIT) occurs for Ru concentrations x~0.75. At t…

Evidence for power-law frequency dependence of intrinsic dielectric response in the CaCuTiO

Alexander Tselev, Charles M. Brooks, Haimei Zheng +4

We investigated the dielectric response of CaCuTiO (CCTO) thin films grown epitaxially on LaAlO (001) substrates by Pulsed Laser Deposition (PLD). The dielectric…
