A test stand to measure the magnetization work of magnetocaloric materials
(Revista De Saude Publica, 2016)
The experimental apparatus presented in this study is capable of precisely measuring the magnetic force produced by a permanent magnets assembly over a magnetocaluric material at a regulated temperature. This data is then ...
Using Proton Nuclear Magnetic Resonance (NMR) as a calibrating reference for magnetic field measurement instruments: Sensitive volume and magnetic field homogeneity
(Elsevier, 2020-02)
Nuclear magnetic resonance can be conveniently used to set up reference values of magnetic flux densities for the calibration of measurement instrumentation. Two measurement procedures are proposed based on the Fourier ...
Evidence of defect-mediated magnetic coupling on hydrogenated Co-doped ZnO
(2013-04-05)
Hydrogenated bulk Zn1-xCoxO samples were synthesized via standard solid-state reaction route with Co molar concentrations up to 15 at.%. Magnetic characterization demonstrates a room temperature ferromagnetic behavior ...

Design studies of the magnetic properties of structural materials affecting the magnetic field of high-homogeneity superconducting magnets
(2001-12-01)
Austenitic stainless steel presents phase changes caused by heat treatment and welding processes. Because it represents a problem in the design of high-homogeneity magnets, we have been studying the magnetic properties of ...

Evolution of soft magnetic, mechanical and electrical properties measured simultaneously during annealing of rapidly solidified alloys
(Elsevier Science, 2019-04-15)
The structure evolution of some soft magnetic metastables alloys are scanned and studied through some room temperature properties changes employing only one sample submitted to successive heat treatments. These are monitored ...
