Terahertz frequency spectrum analysis with a nanoscale antiferromagnetic tunnel junction
P. Yu. Artemchuk, O. R. Sulymenko, S. Louis +7
A method to perform spectrum analysis on low power signals between 0.1 and 10 THz is proposed. It utilizes a nanoscale antiferromagnetic tunnel junction (ATJ) that produces an osci…
Sustained coherent spin wave emission using frequency combs
A. A. Awad, S. Muralidhar, A. Alemán +4
We demonstrate sustained coherent emission of spin waves in NiFe films using rapid demagnetization from high repetition rate femtosecond laser pulse trains. As the pulse separation…
Sub-terahertz ferrimagnetic spin-transfer torque oscillator
Ivan Lisenkov, Roman Khymyn, Johan Akerman +2
A theory of magnetization dynamics in ferrimagnetic materials with antiparallel aligned spin sub-lattices under action of spin-transfer torques (STT) is developed. We consider magn…
Spin-Orbit-Torque Driven Propagating Spin Waves
Himanshu Fulara, Mohammad Zahedinejad, Roman Khymyn +4
Spin-orbit torque (SOT) can drive sustained spin wave (SW) auto-oscillations in a class of emerging microwave devices known as spin Hall nano-oscillators (SHNOs), which have highly…
