The electromagnetic response of a superconducting ferromagnets
The electromagnetic response of the superconducting ferromagnets RuSr₂Gd₁.₅Ce₀.₅Cu₂O₁₀ (Ru–1222 Gd) in an ac magnetic field of finite amplitude is investigated. Taking into account weak links between granules and magnetization of the magnetic sublattice, it is shown that the response of a sample i...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The electromagnetic response of the superconducting ferromagnets RuSr₂Gd₁.₅Ce₀.₅Cu₂O₁₀ (Ru–1222
Gd) in an ac magnetic field of finite amplitude is investigated. Taking into account weak links between granules
and magnetization of the magnetic sublattice, it is shown that the response of a sample in a superconducting
state with the fundamental frequency and frequency of the 3rd harmonic can be described by the
nonlinear equation for the macroscopic field. Generation of the harmonic at temperatures above superconducting
transition corresponds to Rayleigh`s mechanism. Using various regimes of a sample cooling, the internal
magnetic field determined by the magnetic sublattice was measured. This is direct evidence of the coexistence
of ferromagnetic and superconductive order parameters in high-Tc ruthenocuprates. |
