Spin-wave diode and circulator based on unidirectional coupling
Krzysztof Szulc, Piotr Graczyk, Michał Mruczkiewicz +2
In magnonics, an emerging branch of wave physics characterized by low-energy consumption, it is highly desirable to realize circuit elements within the scope of spin-wave computing…
Nonresonant amplification of coherent spin waves through voltage-induced interface magnetoelectric effect and spin-transfer torque
Piotr Graczyk, Maciej Krawczyk
We present new mechanism for manipulation of the spin-wave amplitude through the use of the dynamic charge-mediated magnetoelectric effect in ultrathin multilayers composed of diel…
Spin-polarized currents driven by spin-dependent surface screening
Piotr Graczyk, Maciej Krawczyk
We have examined the spin polarization of the electron current in a ferromagnetic metal induced by the spin-dependent surface screening at the dielectric-ferromagnetic metal (D-FM)…
Experimental Evidence of Non-Negligible Imaginary Part of Spin Mixing Conductance and Its Impact on Magnetization Dynamics in Heavy-Metal|Ferromagnet Bilayers
Adam Krysztofik, Piotr Graczyk, Hubert Głowiński +4
The paper concerns experimental verification of the magnitude of imaginary part of spin mixing conductance in bilayers comprising heavy metals. We present results of broadband ferr…
Magnonic band gap and mode hybridization in continuous Permalloy film induced by vertical coupling with an array of Permalloy ellipses
Piotr Graczyk, Maciej Krawczyk, Scott Dhuey +3
We investigate magnonic band structure in thin homogeneous permalloy film decorated with periodic array of elliptically shaped permalloy dots and separated by non-magnetic Pt space…
Co- and contra-directional vertical coupling between ferromagnetic layers with grating for short-wavelength spin wave generation
Piotr Graczyk, Mateusz Zelent, Maciej Krawczyk
The possibility to generate short spin waves is of great interest in the field of magnonics nowadays. We present an effective and technically affordable way of conversion of long s…
