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 Mx and My magne...

Description
Summary: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 Mx and My magnetic viscosity signals vary with field and field angle. The Mx magnetic viscosity is maximum in the easy plane and decreases to a factor of two along the macroscopic hard axis of the filament. The My magnetic viscosity is nearly zero along the hard axis and in the easy plane and is maximum for intermediate field angles.
