Modelos não lineares de materiais magnéticos para dispositivos elétromagnéticos
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2016-11-21)
Cores made with magnetic materials are broadly use in several areas of application Electrical Engineering, such as electrical machines and power electronics. Analyzing systems containing these magnetic cores is complex due ...
Embedding CoPt magnetic nanoparticles within a phosphate glass matrix
(2020-12-25)
Glasses are materials with highly flexible compositions and high chemical and physical durability. These characteristics make them suitable materials for hosting nanoparticles for different purposes. Hybrid glasses containing ...
Two-dimensional Ising model with Einstein site phonons
(American Physical Society, 2019-04-23)
We consider a simple Ising magnetic model in two dimensions with Einstein site phonons and study it using Monte Carlo simulations that take into account both degrees of freedom simultaneously. In nonfrustrated systems, ...
Design, manufacturing, and testing of a Nb3Sn coil employing Ti alloy as structural material
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Separating the influence of electric charges in magnetic force microscopy images of inhomogeneous metal samples
(2018-01-15)
In this study, we investigate artifacts arising from electric charges present in magnetic force microscopy images. Therefore, we use two austenitic steel samples with different microstructural conditions. Furthermore, we ...
Intrinsic magnetic properties of BixCo2-xMnO 4 spinels obtained by short-time etching
(2013-08-01)
We report the structural and magnetic properties of Co2MnO 4, partially substituted by Bi at the octahedral site. Bismuth enhances ferromagnetism due to a decrease of the Co2+-Co2+ antiferromagnetic interactions and an ...
