Abstract
Characterization of amorphous ribbon is made by using Vibrating Sample Magnetometry VSM technique with different geometric arrangements: P10, P190, P20 and P290. The purpose is to determine the evolution of the saturation magnetization MS, retentivity MR and magnetic anisotropy K1 as a function of annealing time treatment and also as a function of the geometric arrangement. The rate of change of magnetization ∆M/∆H is determined for orientation P190 and orientation P290. These values of rate of change for the ribbon with no annealing treatment are: 0.122 emu/cm3 and 0.11 emu/cm3, respectively. The highest values of anisotropy are for orientation P190 and for orientation P290, these values are: K1 = 2,365,100 erg/cm3 and K1 = 2,405,520 erg/cm3, respectively. Thus we establish that the amorphous ribbon is a strong candidate for technological applications in the area of the magnetic industry, because they can be designed vector field detectors in three directions: longitudinal, transverse (to the ribbon axis) and normal to ribbon plane.
