Optical heterodyne microscopy of operating spin Hall nano-oscillator arrays
A. Alemán, A. A. Awad, S. Muralidhar +5
Optical heterodyne detection is a powerful technique for characterizing a wide range of physical excitations. Here, we use two types of optical heterodyne detection techniques (fun…
Femtosecond laser comb driven perpendicular standing spin waves
Ahmad A. Awad, Shreyas Muralidhar, Ademir Alemán +3
We study femtosecond laser comb driven sustained and coherent spin wave (SW) generation in permalloy (Py) films over a thickness range of 40--100 nm. A simple rapid demagneti…
Femtosecond laser pulse driven caustic spin wave beams
S. Muralidhar, R. Khymyn, A. A. Awad +4
Controlling the directionality of spin waves is a key ingredient in wave-based computing methods such as magnonics. In this paper, we demonstrate this particular aspect by using an…
A Spin Hall Ising Machine
Afshin Houshang, Mohammad Zahedinejad, Shreyas Muralidhar +3
Ising Machines (IMs) are physical systems designed to find solutions to combinatorial optimization (CO) problems mapped onto the IM via the coupling strengths of its binary spins.…
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…
Two-dimensional mutual synchronization in spin Hall nano-oscillator arrays
Mohammad Zahedinejad, Ahmad A. Awad, Shreyas Muralidhar +5
Spin Hall nano-oscillators (SHNOs) utilize pure spin currents to drive local regions of magnetic films and nanostructures into auto-oscillating precession. If such regions are plac…
