- Implementation of an automated FORC analysis and anisotropy measurements in a homemade VSM P.N. Granell M.R. Pagnola L.G. Pampillo F.D. Saccone Física, Astronomía y Matemáticas magnetic anisotropy First Order Reversal Curves (FORC) Biaxial Vibrating Sample Magnetometer (biaxial VSM) In this paper we describe the implementation of a biaxial vibrating sample magnetometer capable of performing measurements by the First Order Reversal Curve technique in an automated way. This magnetometer was employed for measuring the coefficient of anisotropy in an ALNICO piece. The measured value was K1 = (3.9±0.3) × 105 J/m3 . The interaction fields of this ALNICO sample have been analysed after performing its First Order Reversal Curves diagrams, in parallel and perpendicular to the field anisotropy orientation. For this last orientation, it was detected a low contribution of hysterons to the diagram in the near range of H=0 axis, as it can be expected due to a reduction in the remanence of perpendicular measurements of hysteresis loop. 2012 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57030392067 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
