Structure-property relationships of YbFe₂O₄-type layered transition metal oxides

Creator:

Grajczyk, Rosa

Abstract:

The structure–property relationships of solid solutions within the YbFe₂O₄ family of compounds have been studied in relation to their optical, dielectric and magnetic properties. This family of compounds is of recent interest because of the trigonal bipyramid coordination that is rarely observed in transition metal oxides. The systematic study of...

Structural and magnetic investigation of Fe3+ and Mg2+ substitution into the trigonal bipyramidal site of InGaCuO4

Creator:

Grajczyk, Rosa, Berthelot, Romain, Muir, Sean, Sleight, A. W., and Subramanian, M. A.

Abstract:

The solid solutions of InGa₁₋ₓFeₓCuO₄, InFeCu₁₋ₓMgₓO₄, and InGa₁₋ₓFeₓCu₁₋ₓMgₓO₄ were synthesized and characterized through the use of X – ray and neutron diffraction, and DC – magnetism measurements. All compositions of InGa₁₋ₓFeₓCuO₄ are single phase and crystallize in the R3m space group, but a transformation to the spinel InFeMgO₄ structure was...

Structural and magnetic investigation of In₂Fe₂₋ₓGaₓCuO₇

Creator:

Grajczyk, Rosa, Chan, Adam, Ramirez, A. P., and Subramanian, M. A.

Abstract:

The solid solution of In₂Fe₂₋ₓGaₓCuO₇ (space group P6₃/mmc) was synthesized and investigated through X-ray diffraction and magnetic susceptibility studies. Limited changes to the lattice parameters were observed as a result of the similar ionic radii for Fe³⁺ and Ga³⁺ in the trigonal bipyramidal (TBP) crystallographic site. An increase in the...
