“…For the parent compound both Co-O and Co-O-Co values differ slightly from that given by Zhang et al [8]. This small discrepancy may be explained by the difference in the elaborating method.…”

“…Kuhuns et al [7] studied the 59 Co nuclear magnetic resonance in La 1−x Sr x CoO 3 and observed the coexistence of ferromagnetic, spin-glass and hole-poor low spin regions for 0.1 ≤ x ≤ 0.5. Recently, Zhang et al [8] studied the lattice effects on the magnetic properties of La 0.67−x Gd x Sr 0.33 CoO 3 by partial substitution of La by smaller Gd ions. Gd 3+ doping drives the system from cluster glass state to spin-glass state.…”

“…The Co-O-Co bond angle remains almost constant ( Table 1). The structural parameters obtained for the parent compound are consistent with the literature [29]. The parent compound exhibits a spin-glass behavior at low temperature which originates due to the competition between the ferromagnetic (Co 3+ −O−Co 4+ ) and the antiferromagnetic (Co 3+ −O−Co 3+ and Co 3+ −O− Co 4+ ) interactions [28].…”

Synthesis, and measurement of structural and magnetic properties, of La1−xCdxCoO3 perovskite ceramic oxides

Perovskite-type Cd-doped LaCoO 3 materials were synthesized by a simple solution-based combustion process. The synthesized materials were characterized by powder Xray diffraction (XRD), scanning electron microscopy (SEM), diffuse reflectance (DR) in the UV-VIS, and magnetic property measurements. The parent LaCoO 3 compound showed spin-glass transition at low temperatures, and with progressive Cd doping, showed transition to paramagnetic ordering. The changes in magnetic properties of the materials are correlated to the changes in structural features resulting from the Rietveld structural refinement of the materials.

Here, we report the observation of ferroelectric and ferroelastic nanodomains in (110)-oriented BiFeO3 (BFO) thin films epitaxially grown on low symmetric (100) NdGaO3 (NGO) substrate. We observed long range ordering of ferroelectric 109° stripe nanodomains separated by periodic vertical domain walls in as-grown 130 nm thick BFO films. The effect of La0.67Sr0.33CoO3 (LSCO) conducting interlayer on domain configurations in BFO/NGO film was also observed with relatively short range-ordering of stripe domains due to the modified electrostatic boundary conditions in BFO/LSCO/NGO film. Additional studies on B-site doping of Nb ions in BFO films showed change in the domain structures due to doping induced change in lattice anisotropy while maintaining the stripe domain morphology with 109° domain wall. This long-range array of ferroelectric and ferroelastic domains can be useful for optoelectronic devices and ferroelastic templates for strain coupled artificial magnetoelectric heterostructures.
