Hyperfine local probe study of alkaline-earth manganites SrMnO3 and BaMnO3
J. N. Gonçalves, V. S. Amaral, J. G. Correia +3
We report perturbed angular correlation measurements with 111mCd/111Cd and 111In/111Cd probes, at the ISOLDE-CERN facility, in the manganite compounds BaMnO3 , with the 6H and 15R…
Dynamic and structural properties of orthorhombic rare-earth manganites under high pressure
D. A. Mota, A. Almeida, V. H. Rodrigues +6
We report a high-pressure study of orthorhombic rare-earth manganites AMnO3 using Raman scattering (for A = Pr, Nd, Sm, Eu, Tb and Dy) and synchrotron X-ray diffraction (for A = Pr…
Unravelling the effect of SrTiO3 antiferrodistortive phase transition on the magnetic properties of La0.7Sr0.3MnO3 thin films
D. A. Mota, Y. Romaguera Barcelay, A. M. R. Senos +12
Epitaxial La0.7Sr0.3MnO3 (LSMO) thin films, with different thickness ranging from 20 nm up to 330 nm, were deposited on (100)-oriented strontium titanate (STO) substrates by pulsed…
Structural, electrical and magnetic properties of magnetoelectric GdMnO3 thin films prepared by sol-gel method
Y. Romaguera-Barcelay, J. Agostinho Moreira, A. Almeida +2
In this work, we analysed GdMnO3 magnetoelectric thin films prepared by a general sol-gel method. The film formation temperature is analysed by termogravimetric analysis, while the…
THz and infrared studies of multiferroic hexagonal Y_(1-x)Eu_xMnO_3 (x=0 - 0.2) ceramics
V. Goian, S. Kamba, C. Kadlec +5
We report an investigation of hexagonal Y_(1-x)Eu_xMnO_3 ceramics with x=0, 0.1 and 0.2 using infrared and THz spectroscopies in the temperature range between 5 and 900 K. The temp…
Evidence of random magnetic anisotropy in ferrihydrite nanoparticles based on analysis of statistical distributions
N. J. O. Silva, V. S. Amaral, L. D. Carlos +7
We show that the magnetic anisotropy energy of antiferromagnetic ferrihydrite depends on the square root of the nanoparticles volume, using a method based on the analysis of statis…
Matrix Assisted Formation of Ferrihydrite Nanoparticles in a Siloxane/Poly(Oxyethylene) Nanohybrid
Nuno J. O. Silva, Vitor S. Amaral, Veronica de Zea Bermudez +4
Matrix-assisted formation of ferrihydrite, an iron oxide hydroxide analogue of the protein ferritin-core, in a sol-gel derived organic-inorganic hybrid is reported. The hybrid netw…
NMR evidence for an inhomogeneous transition between the ferromagnetic and antiferromagnetic ground states in PrCaMnO manganites
M. S. Reis, V. S. Amaral, P. B. Tavares +5
The low temperature behavior of PrCaMnO manganites are known to undergo a transition at 0.3, from an insulating ferromagnetic state, at low Ca concentrat…
