摘要: Abstract A modified version of the Stoner–Wohlfarth model, which takes into account thermal effects, has been used to study influence measuring temperature on magnetic anisotropy derived from demagnetization curves. To be able reproduce dependence magnetization curve, and not only coercivity, a Neel relaxation approach is considered, avoiding two-state approximation. Anisotropy results are compared with calculations for field dependent torque magnetometry, indicating that most reliable parameter in apparent distribution mean value field.
