Experimental observation of switching in ferromagnetic nanoscale double disks

We investigated a system of two overlapping ferromagnetic permalloy disks, called a hysteron. For sufficiently small disk diameters the hysteron contains only one vortex which is displaced off the center of the disk hosting it. By swapping the vortex from one side of the disk to the other via an in-plane magnetic field, the magnetization in the appended disk is reversed. The magnetization rever...

Isolating the dynamic dipolar interaction between a pair of nanoscale ferromagnetic disks.

Dynamic dipolar interactions between spin wave eigenmodes of closely spaced nanomagnets determine the collective behavior of magnonic and spintronic metamaterials and devices. However, dynamic dipolar interactions are difficult to quantify since their effects must be disentangled from those of static dipolar interactions and variations in the shape, size, and magnetic properties of the nanomagn...

Magnetization switching in nanoscale ferromagnetic grains: description by a kinetic Ising model

The magnetic relaxation of ferromagnetic powders has been studied for many years, largely due to its importance to recording technologies. However, only recently have experiments been performed that resolve the magnetic state of individual sub-micron particles. Motivated by these experimental developments, we use droplet theory and Monte Carlo simulations to study the time and field dependence ...

Direct observation of spin configuration and classificatio of switching processes in mesoscopic ferromagnetic rings

Using nonintrusive imaging techniques we have directly observed the nanoscopic details of the magnetization configuration of epitaxial and polycrystalline mesoscopic ring structures with a ,15-nm resolution. We have found head to head domain walls with different spin structures depending on ring width. Further, we can classify the geometry dependent switching processes according to the number o...
