The magnetic and electrical properties of available square-loop materials are discussed for applications in cores for magnetic amplifiers, pulse modulators, and memory and switching coils. Among materials having high magnetic induction, oriented 50-50 nickel-iron is outstanding. Its pre-eminence for magnetic amplifier applications can be challenged only by new alloys such as Supermendur. Materials having lower saturation find application in varied fields; e.g., 4-79 Mo-permalloy in fast switching coils, and ferrites in memory arrays.
