Crossover From Individual to Collective Magnetism in Dense Nanoparticle Systems: Local Anisotropy Versus Dipolar Interactions
Elena H. Sánchez, Marianna Vasilakaki, Su Seong Lee +11
Dense systems of magnetic nanoparticles may exhibit dipolar collective behavior. However, two fundamental questions remain unsolved: i) whether the transition temperature may be af…
Simultaneous individual and dipolar collective properties in binary assemblies of magnetic nanoparticles
Elena H. Sánchez, Marianna Vasilakaki, Su Seong Lee +12
Applications based on aggregates of magnetic nanoparticles are becoming increasingly widespread, ranging from hyperthermia to magnetic recording. However, although some uses requir…
