%X The demagnetization curves of Pr2Fe14B nanocrystalline magnets are calculated using micromagnetic finite-element method. The samples with three different distributions of grain size are simulated. The remanence enhancement does not depend on grain size distribution but on the mean diameter of grains. The influence of grain size distribution on coercivity is affected by the strength of intergrain exchange coupling.
