Frequency-Division Multiplexing in Magnonic Waveguides
Alina-Cristina Bunea, Laurentiu Stoleriu, Giacomo Talmelli +3
Frequency-division multiplexing is a key functionality for wave-based information processing, enabling multiple information channels to coexist within the same physical medium. Her…
Correlation between structural and magnetic properties of epitaxial YIG films by pulsed laser deposition
José Diogo Costa, N. Claessens, Giacomo Talmelli +6
In this study, we investigate the relationships between film growth conditions, crystalline microstructure, and magnetic properties of epitaxial Yttrium Iron Garnet (YFeO$_…
Microwave Properties of Ba-Substituted Pb(ZrTi)O after Chemical-Mechanical Polishing
Federica Luciano, Lieve Teugels, Sean McMitchell +13
We have studied the effect of chemical-mechanical polishing (CMP) on the ferroelectric, piezoelectric, and microwave dielectric properties of Ba-substituted PZT (BPZT), deposited b…
Lumped circuit model for inductive antenna spin-wave transducers
Frederic Vanderveken, Vasyl Tyberkevych, Giacomo Talmelli +3
We derive a lumped circuit model for inductive antenna spin-wave transducers in the vicinity of a ferromagnetic medium. The model considers the antenna's Ohmic resistance, its indu…
Reconfigurable 3D magnonic crystal: tunable and localized spin-wave excitations in CoFeB meander-shaped film
A. V. Sadovnikov, G. Talmelli, G. Gubbiotti +5
In this work, we study experimentally by broadband ferromagnetic resonance measurements, the dependence of the spin-wave excitation spectra on the magnetic applied field in CoFeB m…

Florin Ciubotaru, Giacomo Talmelli, Thibaut Devolder +4
We report on the first experimental demonstration of majority logic operation using spin waves in a scaled device with an in-line input and output layout. The device operation is b…
Measuring the dispersion relations of spin wave bands using time-of-flight spectroscopy
T. Devolder, G. Talmelli, S. M. Ngom +3
We develop a generic all-inductive procedure to measure the band structure of spin waves in a magnetic thin stripe. In contrast to existing techniques, our method works even if sev…
Magnonic band structure in CoFeB/Ta/NiFe meander-shaped magnetic bilayers
G. Gubbiotti, A. Sadovnikov, E. Beginin +7
In this work, we investigate the spin-wave propagation in three-dimensional nanoscale CoFeB/Ta/NiFe meander structures fabricated on a structured SiO2/Si substrate. The magnonic ba…
Electrical spin-wave spectroscopy in nanoscale waveguides with nonuniform magnetization
Giacomo Talmelli, Daniele Narducci, Frederic Vanderveken +6
Spin waves modes in magnetic waveguides with width down to 320 nm have been studied by electrical propagating spin-wave spectroscopy and micromagnetic simulations for both longitud…
Magnonic band structure in vertical meander-shaped CoFeB thin films
Gianluca Gubbiotti, Alexandr Sadovnikov, Evgeny Beginin +10
The dispersion of spin waves in vertical meander-shaped CoFeB thin films consisting of segments located at 90° angles with respect to each other is investigated by Brillouin light…
BPZT HBARs for bias-tunable, stress generation at GHz frequencies
U. K. Bhaskar, D. Tierno, G. Talmelli +3
The high frequency performance of strong piezoelectric materials like PZT remains relatively less explored due to the assumption of large dielectric/ferroelectric losses at GHz fre…
Reconfigurable sub-micron spin-wave majority gate with electrical transducers
Giacomo Talmelli, Thibaut Devolder, Nick Träger +10
Spin waves are excitations in ferromagnetic media that have been proposed as information carriers in hybrid spintronic devices with much lower operation power than conventional cha…
Experimental Realization of a Passive GHz Frequency-Division Demultiplexer for Magnonic Logic Networks
