【Abstract】 Spin torque nano-oscillator(STNO) is a new microwave oscillator which produces microwave output signal by combining the magnetoresistance effect and precession of magnetic moment in free magnetic layer induced by spin polarized current in multilayered magnetic nanostructures.It’s a promising candidate for future RF transceivers due to its advantages of small volume,oscillation frequency tuned by current and high quality factor and low power consumption.The paper introduces the working principle of STNO,the domestic and foreign research present situation,development trend and the application prospect.更多还原
