Bi-isotropic effects on hybrid surface polaritons in bilayer configurations
A. Nonato, Pedro D. S. Silva
In this work, we investigate the bi-isotropic effects in the formation and tunability of hybrid surface polaritons in bilayer configurations. We consider a heterostructure composed…

A. Nonato, R. X. Silva, C. C. Santos +2
Tetramethylammonium (TMA) cadmium azide, is a new perovskite-like compound which undergoes a series of first-order phase transitions, including a ferroelastic transition above room…
Resonant Raman Scattering and Optical Absorption Studies of Zn(II) Impurities in L-Alanine Single Crystal
A. Nonato, G. G. S. Teles, C. C. Silva +5
We present a study of low-concentration Zn (II) impurities in L-Alanine Single Crystal (ZNLA) employing resonant Raman scattering and optical absorption spectroscopy. By analyzing…
Tuning Electric Polarization via Exchange Striction Interaction in CaMnO by Sr-Doping
A. Nonato, S. Y. Vilar, J. Mira +6
Magnetoelectric (ME) materials displaying strong magnetically induced polarization have attracted considerable interest due to their potential applications in spintronics and vario…
Strong Electron-Phonon Coupling and Lattice Dynamics in One-Dimensional [(CH3)2NH2]PbI3 Hybrid Perovskite
A. Nonato, Juan S. Rodríguez-Hernández, D. S. Abreu +8
Hybrid halide perovskites (HHPs) have attracted significant attention due to their remarkable optoelectronic properties that combine the advantages of low cost-effective fabricatio…
High-temperature structural phase transition and infrared dielectric features of La2CoMnO6
R. X. Silva, A. Nonato, R. L. Moreira +2
Temperature-dependent FAR-infrared reflectivity spectra of partially ordered magnetodielectric La2CoMnO6 is presented, from room temperature up to 675 K. A clear first-ordered stru…
