Experimentally, the MB nanostructure can be fabricated [11,12] by deposing a nanosized FM material on top of a near-surface two-dimensional electron gas (2DEG) formed in a modulation-doped semiconductor heterostructure, where the FM material provides a magnetic field which can influence locally the motion of the electrons in the semiconductor heterostructure.
