(color online) Magnetic moment distributions of Nd₂Fe₁₄B/α–Fe nanocomposite magnet with S = 40 nm, when (a) H = −2.8 kOe where nucleation occurs, (b) H = −4.2 kOe (b), H = −7.7 kOe before reversal of the whole magnet observation plane (c) perpendicular and (d) parallel to the easy axis. Observation surfaces of panels (a), (b) and (c) are xy plane and z = 28 nm while observation surfaces of panel (d) is xz plane and y = 28 nm.
