Abstract EN
A theoretical model for the real and imaginary parts of the susceptibility of superconducting thin disk as a function of a perpendicular applied magnetic field were derived.
In order to do the calculation according to this model, matlab codes were written.
The calculation was done with the assumption that the critical current density is independent of the applied magnetic field (The Bean critical state Model).
The real and imaginary parts of susceptibility was then calculated at different films thickness and at different critical current densities.
The calculation was repeated with the assumption that the critical current densities are magnetic field dependent by using the concepts of Kim and Exponential models.
It was found that the magnetic field of full penetration increases linearly as the disk thickness increases, ^p — 0-9267d + 1.
0984 for the Bean Model, Hp — 17.772d + 132.13 for the Exponential model, and Hp — 19.363d — 159.83 for Kim model.
Moreover, the magnetic field of full penetration increases linearly as the critical current densities increases.
The results of using the ac susceptibility model showed agreement with some of published works.
