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…
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…
Hyperfine Interactions in MnAs studied by Perturbed Angular Correlations of -Rays using the probe BrSe and first principles calculations for MnAs and other Mn pnictides
J. N. Gonçalves, V. S. Amaral, J. G. Correia +1
The MnAs compound shows a first-order transition at T C, and a second-order transition at T C. The first-order transition, with structural (hexagonal-ort…
PAC study of the static and dynamic aspects of metal atom inside C60 cage
S. K. Das, R. Guin, D. Banerjee +5
30 keV 111mCd and 50 keV 199mHg beams from ISOLDE were used to implant on preformed target of C60 with the thickness of 1 mg/cm2. Endofullerene compounds, viz.,111mCd@C60 and 199mH…
Ab-initio study of the relation between electric polarization and electric field gradients in ferroelectrics
J. N. Gonçalves, A. Stroppa, J. G. Correia +4
The hyperfine interaction between the quadrupole moment of atomic nuclei and the electric field gradient (EFG) provides information on the electronic charge distribution close to a…
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…
