Strain engineering of the magnetic anisotropy and magnetic moment in NdFeO3 epitaxial thin films
Mohamed Ali Khaled, Juan Ruvalcaba, Teodoro Cordova +8
Strain engineering is a powerful mean for tuning the various functionalities of ABO3 perovskite oxide thin films. Rare-earth orthoferrite RFeO3 materials such as NdFeO3 (NFO) are o…
Origin and stability of the dipolar response in a family of tetragonal tungsten bronze relaxors
Andrei Rotaru, Donna C. Arnold, Aziz Daoud-Aladine +1
A new family of relaxor dielectrics with the tetragonal tungsten bronze structure (nominal composition Ba6M3+Nb9O30, M3+ = Ga, Sc or In) were studied using dielectric spectroscopy…
Incorporation of lanthanide ions into lead titanate
A. Pelaiz-Barranco, Y. Mendez-Gonzalez, D. C. Arnold +2
A series of lanthanide, Ln, ion doped lead titanate ceramics, at 2 and 8 at.%, have been prepared with starting compositions Pb1-3x/2LnxTiO3, Ln = La, Nd, Sm, Eu, Gd, Dy, using a s…
The beta to gamma (insulator-metal) transition in BiFeO3
Donna C. Arnold, Kevin S. Knight, Gustau Catalan +4
High temperature powder neutron diffraction experiments have been conducted around the reported beta-gamma, insulator-metal phase transition (~ 930 C) in BiFeO3. The results demons…
The ferroelectric-paraelectric phase transition in BiFeO3: crystal structure of the orthorhombic beta-phase
Donna C. Arnold, Kevin S. Knight, Finlay D. Morrison +1
A detailed investigation using variable temperature powder neutron diffraction demonstrates that BiFeO3 undergoes a phase transition from the ferroelectric alpha phase (rhombohedra…
