"information transmitted using magnetic wave motion in complex networks... external stimuli used in spintronics also create/ control spin waves/ ripples in material's magnetization travelling with specific phase/ energy, enabling phase controlled mutual synchronization between 2 spin-Hall nano-oscillators... spin waves mediate both in/ out of phase between oscillators, enabling next-gen Ising machines, an alternative to quantum computers, although best guess/ not exact answers for combinatorial optimisation problems"
