Las propiedades morfológicas y estructurales de las muestras fueron caracterizadas usando difracción de rayos X y microscopía electrónica de barrido (SEM). La presencia de impurezas ha sido descartada a partir de resultados de espectrometría de dispersión de energía de rayos X (EDS). El tamaño promedio de los cristalitos ha sido determinado usando el método de refinamiento de Rietveld de los patrones de difracción. Los resultados sugieren que las características de los lazos de histéresis dependen del proceso de obtención de las muestras, el que no sólo influye en el tamaño de grano sino también puede inducir formas y micro tensiones residuales anisotrópicas.Instituto de Física La PlataFacultad de IngenieríaConsejo Nacional de Investigaciones Científicas y Técnicas2016-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArticulohttp://purl.org/coar/resource_type/c_6501info:ar-repo/semantics/articuloapplication/pdf56-59http://sedici.unlp.edu.ar/handle/10915/96973spainfo:eu-repo/semantics/altIdentifier/url/https://ri.conicet.gov.ar/11336/64987info:eu-repo/semantics/altIdentifier/url/http://anales.fisica.org.ar/journal/index.php/analesafa/article/view/2090info:eu-repo/semantics/altIdentifier/issn/0327-358Xinfo:eu-repo/semantics/altIdentifier/hdl/11336/64987info:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by-nc-sa/4.0/Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)reponame:SEDICI (UNLP)instname:Universidad Nacional de La Platainstacron:UNLP2024-05-08T12:58:14Zoai:sedici.unlp.edu.ar:10915/96973Institucionalhttp://sedici.unlp.edu.ar/Universidad públicaNo correspondehttp://sedici.unlp.edu.ar/oai/snrdalira@sedici.unlp.edu.arArgentinaNo correspondeNo correspondeNo correspondeopendoar:13292024-05-08 12:58:14.339SEDICI (UNLP) - Universidad Nacional de La Platafalse |
