Magnetization relaxation of interacting chains of nanomagnets
This study investigates how magnetic moments in one-dimensional chains of nanomagnets relax over time when subjected to an external field. Researchers used analytical methods and simulations to find relaxation rates and magnetization curves, revealing a transition from uniform reversal at zero field to edge-nucleation dynamics when a field is applied. This shows that spatial differences in dipolar interactions control how the chain switches its magnetic state.
