BH curves of Anisotropic Alnico Magnets

This paper presents the measurement results of the BH curve of the Alnico 8 (LNGT40) with recoil loops. The measurements were handled in a Vibrating Sample Magnetometer (VSM). The magnet samples have a cubic shape with 3 mm sides. BH curves in preferred (easy) and transverse (hard) directions and recoil loops were measured and compared to Alnico 9 as well as to the data from the supplier. The loading point of the cubic magnet in 0 A/m applied magnetic field was found.
