DESCRIPCIÓN E IMPLEMENTACIÓN DE UN MAGNETÓMETRO KERR CONVENCIONAL JAVIER I. TORRES OSORIO BEATRIZ CRUZ MUÑOZ Ingeniería Kerr Ex situ señales materiales magnetómetro Se presenta un magnetómetro Kerr ex situ (MEK), en configuración convencional, que opera bajo condiciones ambientales normales en un rango de 0.0 a 1000 mT ±0,2%. Este equipo es producto del análisis de las señales implícitas en este efecto magnetoóptico y del estudio instrumental realizado a los tipos de MEK identificados. Además se describen los componentes que lo conforman. Para la prueba del magnetómetro, se realizaron mediciones a una muestra de Permalloy (NiFe), material que ha sido previamente medido, con el magnetómetro Kerr diferencial (D-MOKE) del Grupo de Estado Sólido de la Universidad de Antioquia. 2008 artículo científico 0122-1701 https://www.redalyc.org/articulo.oa?id=84903815 es http://www.redalyc.org/revista.oa?id=849 Scientia Et Technica application/pdf Universidad Tecnológica de Pereira Scientia Et Technica (Colombia) Num.38 Vol.XIV
