  • Magnetic element with dual magnetic states and fabrication method thereof
    Patent number: 6233172
    Abstract: An improved and novel magnetic element (10; 10′; 50; 50′; 80) including a plurality of thin film layers wherein the bit end magneto-static demagnetizing fields cancel the total positive coupling of the structure to obtain dual magnetic states in a zero external field. Additionally disclosed is a method of fabricating a magnetic element (10) by providing a plurality of thin film layers wherein the bit end magneto-static demagnetizing fields of the thin film layers cancel the total positive coupling of the structure to obtain dual magnetic states in a zero external field.
