Dynamic characteristics of Co-rich amorphous magnetic cores based on the control magnetization curve

Dynamic characteristics of Co-rich amorphous magnetic cores have been examined based on the Control Magnetization Curve (CMC). Frequency dependence of CMC for amorphous and other soft magnetic cores has also been examined up to f=20kHz. It is found that amorphous cores have many advantages as magnetic materials used for instrumentation and control devices which operate in a high frequency region.
