MAGNETIC MEMORY CELL AND MAGNETIC RANDOM ACCESS MEMORY

摘要

A magnetic memory cell is provided with a fixing layer (4), a recording layer (2), a nonmagnetic layer (3), an electrode section (21) and an electrode section (22). The fixing layer (4) includes a ferromagnetic body whose magnetization direction is fixed. The recording layer (2) includes a ferromagnetic body for storing information by relative relationship between the magnetization direction of the fixing layer (4) and the magnetization direction of the recording layer itself. The nonmagnetic layer (3) is arranged between the recording layer (2) and the fixing layer (4). The electrode section (21) is electrically connected to one end portion of the recording layer (2). The electrode section (22) is electrically connected to the other end portion of the recording layer (2). When a write current is supplied from one of the first electrode section (21) and the electrode section (22) to the other through the recording layer (2), end portion magnetization including a component not parallel to the magnetization direction of the recording layer (2) is generated at the one end portion and the other end portion, and magnetization of the recording layer (2) directs to the direction of the end portion magnetization.
