In the present work, we have modeled a heterogeneous Magneto Resistance Tilted Polarizer-based Spin Torque Nano Oscillator [MRTP-STNO] theoretically. The idea of the work is to investigate the impact of thermal noise on the frequency as well the PSD of the above mentioned device by including the Hth in the Heff. The precession of magnetization dynamics led by Spin Transfer Torque [STT] is studied numerically by solving the equation called Landau-Lifshitz-Gilbert-Slonczewski [LLGS]. Here, β is the independent tilt angle of the fixed layer and θ is the angle between free layer magnetization and the easy axis of the device, respectively. Both the angles can be varied from 10° to 90° as an increment of 10°. The maximum frequency of the modeled device is about 235.5 GHz and PSD of 1.74 µW/mA2/GHz in the absence of thermal noise and in the presence of thermal noise the frequency as well as the corresponding PSD is recorded as 215.4 GHz and PSD of 1.70 µW/mA2/GHz. The author sparks that the modeled device applies to High-Frequency applications and opens a new platform for forthcoming devices during its practical usage. [ABSTRACT FROM AUTHOR]

In this study, we have modeled a simple Spin Torque Nano Oscillator [STNO] of Tri and Penta layer structure theoretically, using macro-spin approach. Tri-layer Spin Torque Nano Oscillator [T-STNO], refers to a device made up of three layers comprising of a couple of Ferro-Magnetic layers separated between a Non-Magnetic [NM] spacer (i.e.) [FM1/NM1/FM2]. Penta-layer Spin Torque Nano Oscillator [P-STNO] refers that the device is made up of five layers which comprised of three FM layers aligned between two NM spacer (i.e.) [FM1/NM1/FM2/NM2/FM3]. The idea of the work is to investigate and report the results of the P-STNO, (which grabbed many researchers' attention) and to compare its functionalities with the conventional T-STNO which has been commercialized, already. The magnetization precession dynamics led by Spin Transfer Torque [STT] is studied numerically by solving the equation called Landau-Lifshitz-Gilbert-Slonczewski [LLGS]. The author wishes that the designed P-STNO device open a new window for the spintronic based devices because of its superior output functionalities as compared to the conventional T-STNO device.

Here, tShe authors have designed a heterogeneous Current Induced Oersted Field based Magneto Resistance Tilted Polarizer-Spin Torque Nano Oscillator [CIOF-MRTP-STNO] in a theoretical manner. The idea of the work is to investigate the impact of thermal noise on the frequency as well the PSD of the above modelled device by including the Hth in the Heff by macro-magnetic approach. The magnetization precession dynamics guided by Spin Transfer Torque [STT] is studied numerically by solving the governing equation called Landau-Lifshitz-Gilbert-Slonczewski [LLGS]. Here, β is the independent tilt angle of the fixed layer and θ is the angle between free layer magnetization and the easy axis of the device, respectively. In the device, both the angles β and θ can be varied from 10° to 90° as an accretion of 10°. The maximum frequency of the modeled device is about 197 GHz and PSD of 1.67 µW/mA2/GHz in the presence of thermal noise with Hoe = 50 kA/m (in the presence of CIOF), but in the absence of thermal noise, the frequency and the PSD emitted by the device is reduced to 180 GHz and 1.63 µW/mA2/GHz. On the other hand, in the presence of thermal noise with Hoe=0 kA/m (in the absence of CIOF), the device emits the frequency and PSD of 137 GHz and 1.51 µW/mA2/GHz, but in the absence of thermal noise, the frequency and the PSD emitted by the device is reduced to 125 GHz and 1.48 µW/mA2/GHz. The author suggests that the modeled device is applicable to High-Frequency applications. [ABSTRACT FROM AUTHOR]
