In this book, We formulate a model to describe the relaxation of single domain magnetic nanoparticles to incorporate the effect of dipolar interaction as well as particle size distribution on the measured relaxation spectra and irreversible, nonequilibrium magnetization response in field-cooled (FC) and zero-field-cooled (ZFC) cases. Further, we analyze the slow dynamics and concomitant memory (aging) effects seen in nanomagnetic systems on the basis of two separate paradigms: superparamagnets and spinglasses. Then, we study the long-time behaviour of an underdamped Brownian particle moving...
