Title: | Capacitance effect on the oscillation and switching characteristics of spin torque oscillators | Authors: | Zeng, T Zhou, Y Leung, CW Lai, PPT Pong, PWT |
Issue Date: | 2014 | Source: | Nanoscale research letters, 2014, v. 9, 597, p. 1-8 | Abstract: | We have studied the capacitance effect on the oscillation characteristics and the switching characteristics of the spin torque oscillators (STOs). We found that when the external field is applied, the STO oscillation frequency exhibits various dependences on the capacitance for injected current ranging from 8 to 20 mA. The switching characteristic is featured with the emerging of the canted region; the canted region increases with the capacitance. When the external field is absent, the STO free-layer switching time exhibits different dependences on the capacitance for different injected current. These results help to establish the foundation for capacitance-involved STO modeling. | Keywords: | Capacitance effect Oscillation frequency Canted region Switching time |
