WebSep 9, 2011 · Relative complex permeability spectra ( μ r = μ r ′ - i μ r ′ ′) and the dc magnetic field effect on them for a yttrium iron garnet (YIG) and its granular composite materials have been studied to evaluate the negative permeability characteristics. WebIt is an iron alloy with silicon as the main additive element (instead of carbon). The exact formulation is tailored to produce specific magnetic properties: small hysteresis area resulting in low power loss per cycle, low core loss, and high permeability. Electrical steel is usually manufactured in cold-rolled strips less than 2 mm thick.
