Unifying Magnetic, Electrical, and Thermoelectric Responses in a Non-Collinear Antiferromagnet
André José, Adrielson Dias, Carlos Eduardo +6
Non-collinear antiferromagnets offer unconventional routes for controlling magnetic, electrical, and thermoelectric responses through their complex spin configurations and interfac…
Resonantly Enhanced Phonon Transport by Magnon Pumping in a Ferromagnetic/Piezoelectric Bilayer
André José, Carlos Eduardo, Adrielson Dias +2
We report the first experimental observation of resonantly enhanced propagating phonon transport induced by magnon pumping in a ferromagnetic/piezoelectric bilayer. Surface acousti…
Controlling magnetic damping with spintronic thermal effects in Py/Fe3O4-PANI bilayers
José Laurentino, Carlos Eduardo, Luiza Paffer +2
We report experiments that control magnetic damping in Py/Fe3O4-PANI via two spintronic thermal effects: spin Seebeck and anomalous Nernst. Magnetic damping is measured using ferro…
New method of image processing via statistical analysis for application in intelligent systems
Monalisa Cavalcante, José Araújo, José Holanda
Image processing has always been a topic of significant importance to society. Recently, this field has gained considerable prominence due to the development of intelligent systems…
Observing a quantum magnetic effect in CaYAl3O7-X particles (X=Ni, Fe, Co)
Luana Hildever, José Laurentino, José Araújo +2
Yttrium calcium aluminate, with the formula CaYAl3O7, has been extensively researched due to its remarkable luminescent properties when doped or co-doped. Additionally, it exhibits…
Robust Partial Quadratic Eigenvalue Assignment Problem: Spectrum Sensitivity Approach
José Mário Araújo, Carlos Eduardo Trabuco Dórea, Luiz Marcos Garcia Gonçalves +2
We propose an optimization approach to the solution of the partial quadratic eigenvalue assignment problem (PQEVAP) for active vibration control design with robustness (RPQEVAP). T…
