Patent ID: 6906949

Claim:
A magnetic element comprising: a first magnetic reference part including a fist ferromagnetic substance pinned in magnetization substantially in a first direction; a second magnetic reference part including a second ferromagnetic substance pinned in magnetization substantially in a second direction; a magnetic recording part provided between the first and second magnetic reference parts, and including a third ferromagnetic substance; a spin transfer intermediate part provided between the first magnetic reference part and the magnetic recording part; and an intermediate part provided between the second magnetic reference part and the magnetic recording part, wherein a magnetization of the third ferromagnetic substance being directed in a direction parallel or anti-parallel to the first direction by passing a writing current between the first magnetic reference part and the magnetic recording part, and wherein a relative relation between the second direction and the direction of the magnetization of the third ferromagnetic substance being detected by passing a sense current between the second magnetic reference part and the magnetic recording part.
