Ferrite Synthesis

Abstract

A systematic investigation of the MgO•MnO•Fe[subscript 2]O[subscript 3] system has indicated that rectangular hysteresis loops can be obtained over a wide range of composition. Maximum squareness is obtained in the region of 33-percent MgO, 25-percent Mno, and 42-percent Fe[subscript 2]O[subscript 3]. A composition of 35-percent MgO, 30-percent Mno, and 35-percent Fe[subscript 2]O[subscript 3] appears best for coincident-current memory applications. Relationships between composition, squareness, coercive force, and switching time are indicated.
