Magnetic Characteristics of an Oriented 50 Percent Nickel-Iron Alloy

Single crystal magnetic properties have been closely approached in a polycrystalline 50 percent nickel-iron by the development of a favorable grain orientation. The method is adapted to commercial production by careful control of processes effecting the fundamental magnetization process in the magnetic domain. Elimination of steps I and III of the normal magnetization has produced a nearly geometrically true rectangular shape of the hysteresis loop.
