Phenomenology of vector-like leptons with Deep Learning at the Large Hadron Collider
Felipe F. Freitas, João Gonçalves, António P. Morais +1
In this paper, a model inspired by Grand Unification principles featuring three generations of vector-like fermions, new Higgs doublets and a rich neutrino sector at the low scale…
Experimental and theoretical study of electronic and hyperfine properties of hydrogenated anatase (TiO): defects interplay and thermal stability
D. V. Zyabkin, H. P. Gunnlaugsson, J. N. Goncalves +13
In this study we report on the results from emission Fe Mssbauer Spectroscopy experiments, using dilute Mn implantation into pristine (TiO) and hydrogenated…
Magnetovolume Effects in Heusler Compounds via First-Principles Calculations
J. N. Gonçalves, J. S. Amaral, V. S. Amaral
Heusler alloys are promising for several applications, including magnetic refrigeration, due to high magnetocaloric and magnetovolume effects. One way to optimize this potential is…
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…
Volume dependence of magnetic properties in Co2Cr1-xYxGa (Y=Ti-Ni) Heusler alloys: a first-principles study
J. N. Gonçalves, N. M. Fortunato, J. S. Amaral +1
The magnetic properties tuning and volume dependence in the series of quaternary full Heusler alloys with formula Co2Cr1-xYGa (Y = Ti, V, Mn, Fe, Co, Ni) were studied with a detail…
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…
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…
