Magnetic sensor, magnetic head, and magnetic memory by using spin hall devices

A magnetic sensor reduces thermal fluctuation and realizes high-sensitive signal detection using a spin Hall device of a simple structure configured with only one magnetic layer. The magnetic sensor includes a stacked film in which a nonmagnetic spin Hall layer, a nonmagnetic insulator layer, and a magnetic layer are stacked, an electrode nonmagnetic terminal pair connected to a side surface of the nonmagnetic spin Hall layer, and a unit applying a current in a film thickness direction of the stacked film. A thickness of the nonmagnetic spin Hall layer is thinner than twice a spin diffusion length of a material constituting the nonmagnetic spin Hall layer. A magnetization direction of the magnetic layer magnetized by an external magnetic field is detected due to the polarity of a voltage across both ends of the electrode nonmagnetic terminal pair.

A record carrier (1) has a servo track (4) indicating an information track (9) intended for recording information blocks represented by marks, this servo track (4) having a periodic variation of a physical parameter. Due to cross-talk, there exists a variation in the wobble signal called wobble beat. The track pitch t and the wobble period p, p being the length of a wobble period, are chosen in such a way that 2πt / p≈n+½ where n is integer. The choice results in a reduced wobble beat. A recording and / or playback device has apparatus for recording / reading the information blocks and for generating a wobble signal.
