Abstract:

An instrument has been designed for the examination of the switching and hysteresis properties of ferrites intended for use in microwave devices of the latching type. The hysteresigraph presents hysteresis loops at audio frequencies, in a form suitable for accurate measurement of magnetization properties. The maximum magnetic field amplitude available is normally about 500 oersteds, which is large compared with the coercive fields of typical materials. Design and performance of the electromagnet, sensing apparatus, and integrating circuits are discussed, and representative data are presented.
