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…
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…
