(color online) The dependence of
on the maximum reversal field HR for (a) the single-phase magnets with different grain size and (b) the nanocomposite magnets with different soft-phase layer thickness while keeping L = 20 nm. The exchange energy distribution along (c) two adjacent hard grains for the single-phase magnet and (d) two adjacent hard grains through the soft-phase layer for the nanocomposite magnet. θ is the angle between two easy-axis directions of the adjacent magnetically hard grains.[267] |
