Remanence enhancement has been calculated for a range of configurations, including 1D (one-dimensional), 2D and 3D arrays of hard magnetic grains, composites of hard and soft magnetic grains and triple-films. A linear relationship between the remanence Mr and the reduced domain wall width W/L has been derived analytically, which is consistent with available experimental and numerical data. For composite materials with a soft phase inserted among hard phases, the soft grain behaves like a massive inter-grain domain-wall and results in more effective remanence enhancement. In view of this, a unified formula is reached which can be applied to both composite and single phased magnets with in-plane random easy axis distribution.
