Spin-wave softening across the uniform-to-stripe domain transition in iron garnet film
Titiksha Srivastava, Victor Leroy, Nessrine Benaziz +6
Spin-wave spectra across transitions between uniform and textured phases can offer deep insight into both symmetry-breaking physics and self-assembled magnonic bands. However, expe…
Magnonic crystalline properties of stripe textures in thin ferromagnetic films
Joo-Von Kim, Victor Leroy, Titiksha Srivastava
Ordered stripe domains in ferromagnetic thin films form a natural one-dimensional crystal for propagating spin waves. Their spatial periodicity can be tuned readily with an applied…
Nonlinear mode interactions under parametric excitation in a YIG microdisk
Gabriel Soares, Rafael Lopes Seeger, Amel Kolli +13
A pair of quantized spin-wave modes is driven by two-tone parallel pumping in a YIG microdisk. The nonlinear dynamics is experimentally investigated by probing the resulting steady…
Degenerate and non-degenerate parametric excitation in YIG nanostructures
Hugo Merbouche, Ping Che, Titiksha Srivastava +10
We study experimentally the processes of parametric excitation in microscopic magnetically saturated disks of nanometer-thick Yttrium Iron Garnet. We show that, depending on the re…
Complete identification of spin-wave eigenmodes excited by parametric pumping in YIG microdisks
Titiksha Srivastava, Hugo Merbouche, Igor Ngouagnia Yemeli +15
We present the parametric excitation of spin-wave modes in YIG micro-disks via parallel pumping. Their spectroscopy is performed using magnetic resonance force microscopy (MRFM), w…
Densely packed skyrmions stabilized at zero magnetic field by indirect exchange coupling in multilayers
Fernando Ajejas, Yanis Sassi, William Legrand +6
Room-temperature stabilization of skyrmions in magnetic multilayered systems is the result of a fine balance between different magnetic interactions namely symmetric and antisymmet…
Resonant dynamics of skyrmion lattices in thin film multilayers: Localised modes and spin wave emission
Titiksha Srivastava, Yanis Sassi, Fernando Ajejas +9
The spectral signatures of magnetic skyrmions under microwave field excitation are of fundamental interest and can be an asset for high frequency applications. These topological so…

Yuma Jibiki, Minori Goto, Eiiti Tamura +9
The fabrication of a skyrmion circuit which stabilizes skyrmions is important to realize micro- to nano-sized skyrmion devices. One example of promising skyrmion-based device is Br…

Titiksha Srivastava, Willy Lim, Isabelle Joumard +3
Skyrmions are chiral magnetic textures that have immense potential for applications in spintronic devices. However, their formation is quite challenging and necessitates a subtle b…
Creation of Magnetic Skyrmion Bubble Lattices by Ultrafast Laser in Ultrathin Films
Soong-Geun Je, Pierre Vallobra, Titiksha Srivastava +10
Magnetic skyrmions are topologically nontrivial spin textures which hold great promise as stable information carriers in spintronic devices at the nanoscale. One of the major chall…
Large voltage tuning of Dzyaloshinskii-Moriya Interaction: a route towards dynamic control of skyrmion chirality
Titiksha Srivastava, Marine Schott, Roméo Juge +14
Electric control of magnetism is a prerequisite for efficient and low power spintronic devices. More specifically, in heavy metal/ ferromagnet/ insulator heterostructures, voltage…
