Frequency Modulation of a Nano-Oxide Layer-Based Spin-Torque Oscillator With FeCo Nanocontacts
We studied the effect of injecting a low-frequency (0.5-1 GHz) ac signal on the natural oscillations of a nano-oxide layer-based nanocontact magnetoresistive spin-torque oscillator with multiple
Frequency modulation of spin torque oscillator pairs
The current controlled modulation of nanocontact based spin torque oscillator (STO) pairs is studied in both the synchronized and nonsynchronized states. The synchronized state shows a well behaved
Modulation of Individual and Mutually Synchronized Nanocontact-Based Spin Torque Oscillators
We study current modulation of spin torque oscillators (STOs) based on single and double nano-contacts. For single nano-contact devices, we show modulation for a carrier frequency of 19-40 GHz and
Modulation-mediated unlocking of a parametrically phase-locked spin torque oscillator
Modulation of an oscillator is crucial for its application in communication devices. While the output power and linewidth of single magnetic tunnel junction-based spin-torque oscillators (MTJ-STO)
Spin-torque oscillator linewidth narrowing under current modulation
We study the behavior of the linewidth of a nanocontact based spin torque oscillator (STO) under application of a radio frequency (100 MHz) modulating current. We achieve a significant (up to 85%)
Frequency enhancement and power tunability in tilted polarizer spin-torque nano-oscillator
In the absence of an applied magnetic field, a spin-torque nano oscillator(STNO) with a tilted polarizer is studied using numerical simulation of the associated Landau-Lifshitz-Gilbert-Slonczewski
Multiple modes of a single spin torque oscillator under the non-linear region
A numerical investigation is conducted for a single spin-torque oscillator under the non-linear region. A large angle precession triggers the generation of multiple modes without any feedbacked
Intrinsic frequency doubling in a magnetic tunnel junction–based spin torque oscillator
We show that the frequency of a magnetic tunnel junction (MTJ)-based spin torque oscillator (STO) can be doubled and the first harmonic entirely suppressed by orienting the free and fixed layer
Spin-Torque and Spin-Hall Nano-Oscillators
The potential for these oscillators in a wide range of applications, from microwave signal sources and detectors to neuromorphic computation elements, is discussed together with the specific electronic circuitry that has so far been designed to harness this potential.
Spin Torque Oscillators and RF Currents—Modulation, Locking, and Ringing
We study the interaction between a nano-contact spin torque oscillator (STO) and injected radio-frequency and microwave currents. Modulation of the STO signal is observed over a wide frequency range
