AbstractAs microwave signal generators, the spin transfer nano-oscillator (STNO) based on magnetic skyrmion has attracted huge interest recently. However, the circular magnetic skyrmion-based oscillator only produces a microwave signal with a single oscillation frequency, and detecting the precession of skyrmion in the entire nanodisk is also a challenge. In the paper, we propose an STNO based on elliptical skyrmion, which can simultaneously generate a single frequency or multiple frequency oscillation signal, and the oscillation frequency also can be increased to some extent. Moreover, to reduce the difficulty of detection, the method to restrict elliptical skyrmion moving in a specific orbit is suggested. Our results provide a possible candidate to design the spintronic devices.
