Abstract
A magnetic tunnel junction device and a magnetic memory device. The magnetic tunnel junction device includes a magnetic tunnel junction including a fixed magnetic body, an insulator, and a free magnetic body sequentially stacked and a conducting wire disposed adjacent the free magnetic body of the magnetic tunnel junction to apply in-plane current. The fixed magnetic body has a fixed magnetization direction and is a thin film including a material magnetized directionally perpendicular to a film surface. The free magnetic body has a structure of [auxiliary free magnetic layer/free non-magnetic layer]N/main free magnetic layer, where N is a positive integer greater than or equal to 2 and indicates that an [auxiliary free magnetic layers/free non-magnetic layers] structure is stacked repeatedly N times.
