摘要：

The spectra of internal ac impedance and fluxmetric and energetically effective circular permeabilities are calculated for infinite slab and cylinder in classical and domain models. The domain models assume transverse bar domains for a slab and transverse circular disk domains for a cylinder, with technical magnetization being carried out by domain wall displacements. For each case, a general formula is given together with the low and high-frequency limits, Numerical results are computed accurately from analytical formulas. Quantitative comparisons among different cases are made. Physical concepts and problems of practical significance are discussed on the basis of the results.
