A magnetoresistive element is provided as a spin valve having a synthetic free layer. More specifically, the synthetic free layer includes a low perpendicular anisotropy layer that is separated from a high perpendicular anisotropy layer by a spacer. Thus, the high anisotropy material introduces an out-of-plane component by exchange coupling. The high perpendicular anisotropy material also has low spin polarization. Further, the low anisotropy material positioned closer to the pinned layer has a high spin polarization. As a result, the magnetization of the low anisotropy material is re-oriented from an in-plane direction to an out-of-plane direction. Accordingly, the overall free layer perpendicular anisotropy can be made small as a result of the low anisotropy material and the high anisotropy material. Adjusting the thickness of these layers, as well as the spacer therebetween, can further lower the anisotropy and thus further increase the sensitivity.

A direction detection apparatus transmits radar waves, with resultant reflected waves being received as incident waves by elements of an array antenna. Normally the direction of a target object is calculated based on analyzing respective received signals from the antenna elements, in calculations utilizing an estimated total number of incident wave directions. In an antenna direction adjustment mode, an actual number of target objects, and hence actual number of incident wave directions, is utilized in place of the estimated value, thereby enabling direction detection information to be obtained which does not fluctuate with time, thus facilitating the adjustment.
