Fig. 9From: Percolation Magnetism in Ferroelectric NanoparticlesPercolation radius versus the concentration of defects for two cases: a n 1/n 2 = const, n varies and b n 2 = const, n 1 varies. Points are calculated numerically in the framework of our model, solid curves are based on the formula (1). Points marked with labels correspond to the studied materials (KTaO3 and KNbO3)Back to article page
