Note 1 to entry: The AC magnetization, M(t), under the magnetic field strength of is expanded as:
where and are the real and imaginary parts of the AC magnetic susceptibility for the order n.
Note 2 to entry: The fundamental components and are mostly observed for measurements of superconducting transition.
Note 3 to entry: The AC loss energy density W is given as:
