Abstract  The demagnetization curves of nanocomposite magnets have been calculated using a one-dimensional model. The results are in agreement with experimental results. The shoulders of the demagnetization curve have also been explained based on the model.
Keywords:  nanocomposite magnets      exchange coupling      demagnetization curve
