Time Dependence Of Magnetic Moment Of Strontium-Ferrite Powder Measured With A Biaxial Vibrating Sample Magnetometer (Vsm)

The magnetic hysteresis and viscosity of SrO(Fe2O3)(6)/PA-12 filaments with 5wt% and 26wt% was determined with a biaxial VSM. The hysteresis curves indicate that manufactured samples have a flow induced anisotropy with an easy plane perpendicular to the filament's cylindrical axis. The M-x and M-y magnetic viscosity signals vary with field and field angle. The M-x magnetic viscosity is maximum in the easy plane and decreases to a factor of two along the macroscopic hard axis of the filament. The M-y magnetic viscosity is nearly zero along the hard axis and in the easy plane and is maximum for intermediate field angles.
