Among the massive studies related to spin-torque-induced magnetization dynamics, the spin-torque diode effect has intrigued intensive interests due to its potential application as a radio-frequency detector, which enables us to rectify an alternating current in nanoscale MTJ through synchronizing the current with the resonant oscillation of the TMR. Previous researches [1] mainly focused on improving the sensitivity of the spin-torque diode radio-frequency detector, while the studies aiming to broaden the resonance detection regime are still insufficient. In this work, we proposed a novel spin-torque diode radio-frequency detector structure based on titled fixed-layer MTJ. The results showed that the resonance detection regime could be significantly improved, which is largely conducive to the practical applications of spin-torque diode effect.
