If you select nspin=2 along with some starting magnetization, it means that you are doing LSDA calculations. Usually the final spin polarized results in ferromagnetic systems are not sensitive to the initial magnetization. Hence I would say set your starting magnetization to numbers between 0.5 and 0.8.<br>
