Abstract
Measurements of magnetic properties of thin-film superconductors at 77 K using dc magnetic fields and ac inductance techniques are discussed. The effects of demagnetizing fields on these measurements are analyzed and compared with results for thin ferromagnets. It is shown that for perpendicular magnetic fields opposite effects are predicted and observed for ferromagnets as compared to superconductors.
