dc.description.abstract A detailed investigation of the scaling relations recently proposed [J. d'Albuquerque e Castro, D. Altbir, J. C. Retamal, and P. Vargas, Phys. Rev. Lett. 88, 237202 (2002)] to study the magnetic properties of nanoparticles is presented. Analytical expressions for the total energy of three characteristic internal configurations of the particles are obtained, in terms of which the behavior of the magnetic phase diagram for those particles upon scaling of the exchange interaction is discussed. The exponent η in scaling relations is shown to be dependent on the geometry of the vortex core, and results for specific cases are presented. ©2005 The American Physical Society. en_US
