A strain-driven BiFeO3 (BFO) tetragonal to rhombohedral phase transition is demonstrated in self-assembled BiFeO3-CoFe2O4 (BFO-CFO) nanocomposites on LaAlO3 (110)-oriented substrates with varying thickness. The CFO forms parallel nanoscale fin-shaped structures within a BFO matrix. Out-of-plane latt...

520 |a A strain-driven BiFeO3 (BFO) tetragonal to rhombohedral phase transition is demonstrated in self-assembled BiFeO3-CoFe2O4 (BFO-CFO) nanocomposites on LaAlO3 (110)-oriented substrates with varying thickness. The CFO forms parallel nanoscale fin-shaped structures within a BFO matrix. Out-of-plane lattice strain from the BFO/CFO interfaces stabilizes the BFO rhombohedral-like phase. The BFO exhibits a range of ferroelectric textures including stripe domains and centered domain arrangements, and the magnetic anisotropy of CFO shows a thickness-dependent reorientation.
