Abstract
The study presents a mathematical model of magnetization harmonics for hard II-type thin disk superconductors. According to the critical state model with Jc ~ /H2 in approximation of magnetic field screening in the disk center, the authors have calculated hysteretic magnetization curves and the dependence of real and imaginary components of the first, third and fifth magnetization harmonics on voltage value of variable and static magnetic fields. Variable magnetic field amplitude has a considerable effect on magnetization harmonics amplitudes.
