A magneto-resistive device is provided to detect a magnetic field passing along a crystalline growth axis(z-axis) vertical to the plane connected to a channel and a classifying unit. A magneto-resistive device(1) includes a channel(2), a conductor(6), and a plurality of leads(81,82,83,84,85,86). The channel includes a non-ferromagnetic semiconductor material and is elongated from a first termination(3) to a second termination(4). The conductor includes a non-ferromagnetic material with higher conductivity than the semiconductor material, and connects more than two sections of the channel. The plurality of leads is connected to the channel and becomes distant along the channel. The channel is an elongate channel.
