Ac susceptibility studies of discontinuous Co80Fe20Al2O3 multilayers
Discontinuous metal}insulator multilayers [Co Fe (t)/Al O (3 nm)] are prepared by ion-beam sputtering and investigated by SQUID magnetometry and AC susceptometry. For 1.0)t)1.6 nm, two coexisting subsystems of dipolar coupled nanoparticles are encountered. While a spin-glass-like freezing particulate fraction dominates at t"1.0 nm, a percolating dipolar ferromagnetic fraction becomes increasing...
متن کاملبررسی اثر اندازه پودرهای اولیه در ریز ساختار و خواص بین دانهای ابررساناهای2223(Bi-Pb)
We have studied the effect of precursor powder size on the microstructure and intergranular behavior of polycrystalline Bi2223 superconductors using the XRD, SEM, electrical resistivity and AC susceptibility techniques. Polycrystalline Bi2223 superconductors were prepared from the powders with different milling times. The XRD results show that by decreasing the precursor powder size the Bi2223...
متن کاملSe p 20 02 Scaling of ac susceptibility and nonlinear response in high - temperature superconductors
The magnetic ac susceptibility of high-temperature superconductors is shown to obey some scaling relations. We try to analyse this behavior within the framework of a common nonlinear response function of mixed state.The derived equations for critical current and ac susceptibility (χ(T)) agree with the scaling relations of experimental data.
متن کاملAC Magnetic Susceptibility Technique for the Characterization of High Temperature Superconductors
The absolute magnetic susceptibility as a function of temperature with different amplitude and frequency of the applied field is used to characterize the magnetic properties of high T c – superconductors. In the present work our design of a laboratory-built ac susceptometer based on the mutual inductance method using local facilities is demonstrated and tested. The setup have moment precision o...
