Summary:Numerical simulations of hysteretic ac losses in a bilayer superconductor/ferromagnet heterostructure subject to an oscillating transverse magnetic field are performed within the quasistatic approach, calling upon the ANSYS finite-element software program and exploiting magnetostatic-electrostatic analogs. It is shown that one-sided magnetic shielding of a thin, type-II superconductor strip can lead to an enhancement or, respectively, a reduction of hysteretic ac losses as compared to those for a nonmagnetic support, depending on the amplitude of the applied magnetic field.
