## Description

- description: The thin-film magnetic skyrmion is designed to interact with each other
    as nonlinear response, enabling collective magnetic morphology at the nonequilibrium
    state. We here explore the alternative nonlinear morphology of multiple skyrmions
    induced by the orthogonal two-current injections for the Pt/Co/Ir multilayer platforms.
    The global currents induce polarity-dependent driving and accumulation of skyrmions
    across the whole area of a Hall bar device. Once another local current is injected
    from a micro-meter width ports, dozens of skyrmions follow their polarity manners
    of the local injection, resulting in total modulations of skyrmion population
    governed by a pair of two-current polarities. Such massive morphology tuning at
    the nonlinear region indicates resemblances with a skyrmion Hall effect, where
    current-induced accumulation and depletion create the nonequilibrium distributions
    of skyrmions toward Hall deflections. Our findings propose an alternative controlling
    method of skyrmion population, threshold-like responses, providing analogies with
    neuromorphic architectures and other advanced information-processing technologies.
