  The development of spintronic oscillators is driven by their potential
applications in radio frequency telecommunication and neuromorphic computing.
In this work, we propose a spintronic oscillator based on the chiral coupling
in thin magnetic films with patterned anisotropy. With an in-plane magnetized
disk imprinted on an out-of-plane magnetized slab, the oscillator takes a polar
vortex-like magnetic structure in the disk stabilized by a strong
Dzyaloshinskii-Moriya interaction. By means of micromagnetic simulations, we
investigate its oscillatory properties under applied spin current and, by
placing an ensemble of oscillators in the near vicinity, we demonstrate their
synchronization with different resonant frequencies. Finally, we show their
potential application in neuromorphic computing using a network with six
oscillators.
