Herein we demonstrate the ability to align anisotropic non-magnetically interacting precursors through simple synthesis steps and without using an external field.…”

“…Eu-doped Bi 0.85 Pr 0.15 Fe 0.97 Mn 0.03 O 3 (EPBFO) thin films were grown by off-axis RF magnetron sputtering on FTO/SiO 2 substrates (without any further surface treatment) at 350 C for 5 h using the procedure of previous work. 23 The thin films were annealed at 600 C for 4 h in an air atmosphere and had a thickness of $500 nm. The surface morphology of the coatings was studied using a field emission scanning electron microscope (JSM-7401F, FESEM JEOL).…”

Polycrystalline‐multiferroic Bi0.85Pr0.15‐xEuxFe0.97Mn0.03O3 (0, 0.01, 0.02, 0.03, 0.4, 0.05) thin films were grown on fluorine‐doped tin oxide (FTO)/glass substrate with radio frequency (RF) magnetron sputtering. Rietveld quantitative analysis reveals that whereas the starting materials (nanoparticles [NPs] and ceramics) are composed of tetragonal P4italicmm symmetry, the thin films can lose 80% of this symmetry to become rhombohedral R3c symmetry. The structure evolution from tetragonal to rhombohedral symmetry indicates that the Eu3+ ion acts positively to reduce the tensile residual stress component from 24 to 1.8 MPa in the thin films. The band gap shifts to 2.17 eV by Eu substitution at the A‐site of the perovskite. Scanning electron microscopy (SEM) results show high‐elongated nanocrystals that share parallel facets without porosity. In that morphology, the Eu has a strong influence on reducing the magnetic coercivity from 10.7 to 6.5 kOe, which has been interpreted in terms of local shape anisotropy. Although the magnetic response increases monotonously, the ferroelectric polarization decreases with doping. These changes are explained through local defects created by the evolution of the VO·· concentration that changes significantly by Eu doping.
