Pulse response characteristics of rectangular-hysteresis-loop ferromagnetic materials

MAGNETIC CORES made with rectangular-hysteresis-loop ferromagnetic materials have recently gained prominence as binary elements in digital data-processing machines. The ability of the core to store binary information reliably and without power dissipation, and the ease with which the information can be read out or changed in a few microseconds make the core a useful and versatile component. Wherever they are applicable, magnetic-core circuits offer advantages over vacuum-tube circuits; the cores are rugged, have indefinite life, and require little power. Cores made with rectangular-hysteresis-loop ferromagnetic materials are being used in shift resisters,1 in memory systems,2, 3 and in logical and control circuits.4¿6
