Absence of zero-field-cooled exchange bias effect in single crystalline La2-xAxCoMnO6 (A = Ca, Sr) compounds
C. Macchiutti, J. R. Jesus, F. B. Carneiro +4
Magnetic properties of A2BB'O6 (A = rare or alkaline earth ions; B,B' = transition metal ions) double perovskites are of great interest due to their potential spintronic applicatio…
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…
Lattice dynamics and Raman spectrum of BaZrO3 single crystals
Constance Toulouse, Danila Amoroso, Cong Xin +7
BaZrO3 is a perovskite that remains in the simple cubic phase at all temperatures, hence with no first-order Raman-active phonon mode allowed by symmetry. Yet, it exhibits an inten…
Kagome modes, a new route to ultralow thermal conductivity?
D. J. Voneshen, M. Ciomaga Hatnean, T. G. Perring +4
From next generation gas turbines to scavenging waste heat from car exhausts, finding new materials with ultra-low thermal conductivity () has the potential to lead to large gai…
Investigating the magnetic ground state of the skyrmion host material CuOSeO using long-wavelength neutron diffraction
Kévin J. A. Franke, Philip R. Dean, Monica Ciomaga Hatnean +6
We present long-wavelength neutron diffraction data measured on both single crystal and polycrystalline samples of the skyrmion host material CuOSeO. We observe magneti…
