Hysteresis-free switching between vortex and collinear magnetic states

Hysteresis-free switching between vortex and collinear magnetic states

We demonstrate a lossless switching between vortex and collinear magnetic states in circular FePd disks arranged in a square lattice. Above a bifurcation temperature $\left( {{T}_{\text{e}}} \right)$ we show that thermal fluctuations are enough to facilitate flipping between the two distinctly diffe...
