Abstract
A storage element 3 has an arrangement in which magnetization fixed layers 31 and 32 are provided above and below a storage layer 17 for storing information based on the magnetization state of a magnetic material through intermediate layers 16 and 18, directions of magnetizations M15 and M19 of ferromagnetic layers 15 and 19 closest to the storage layer 17 of the magnetization fixed layers 31 and 32 above and below the storage layer 17 are opposite to each other, the two intermediate layers 16 and 18 above and below the storage layer 17 have a significant difference between sheet resistivity values thereof and in which the direction of a magnetization M1 of the storage layer 17 is changed with application of an electric current to the lamination layer direction to record information on the storage layer 17.
