Magnetic properties of spinel-type oxides NiMn2-xMexO4
(2005-09-01)
New materials, based on the well-known spinel compound NiMn 2O4, have been synthesized and characterized from the magnetic point of view. The manganese cation was partially substituted in the general formula NiMn2-xMexO4, ...

An environmental magnetism approach to assess impacts of land-derived sediment disturbances on coral reef ecosystems (Cartagena, Colombia)
(Pergamon-Elsevier Science Ltd, 2018-06)
We used environmental magnetism methods to study recently deposited marine sediments from the estuarine ecosystems on the Caribbean coast of Colombia. Cartagena region has undergone an increasing sediment load during the ...
Mapeamento do campo magnético dentro do estator de um motor de corrente contínua com ímã permanente utilizando o método dos elementos finitos
(Universidade Tecnológica Federal do ParanáCuritibaBrasilCurso de Engenharia ElétricaUTFPR, 2018-06-14)
In this work, a DC motor with permanent magnets is analyzed through magnetic field analysis. The constructive aspects and phenomena present in the machine are explained in detail before the analysis. This analysis is based ...
Ab initio study on the role of the crystalline symmetry in the stabilization of the magnetic order in Al-doped SnS
(Elsevier Science, 2019-04)
We use firstprinciples calculations to study the electronic and magneticproperties of undoped and Al-doped SnS and their dependence withspace-group symmetry. The formation of a magnetic moment due to animpurity element was ...
