Multiple three-magnon splittings in bismuth yttrium iron garnet nanostructures
Sali Salama, Joo-Von Kim, Maryam Massouras +3
We experimentally demonstrate the generation of multiple three-magnon splitting processes in an in-plane magnetized submicron Bi-YIG disk using micro-focused Brillouin light scatte…
Experimental determination and micromagnetic analysis of spin wave modes in cylindrical nanowires
Niklas Martin, Laura Álvaro-Gómez, Lucas Perez +4
We report an experimental study of spin wave modes in individual cylindrical nanowires, a textbook situation of confined spin waves in 3D nanomagnetism. We observe discrete modes o…
Method of analysis of the spectra obtained by microfocused Brillouin light scattering
Nessrine Benaziz, Thibaut Devolder, Jean-Paul Adam
Brillouin Light Scattering is a powerful technique to measure the microwave excitations present in a magnetic system. In microfocused mode, the light is focused on the sample using…
Role of non-reciprocity in spin-wave channeling
Jean-Paul Adam, Nathalie Bardou, Aurélie Solignac +2
The extent to which non-reciprocal waves can be guided in arbitrary directions is an interesting question. We address one aspect of this problem by studying the propagation of acou…
Large frequency nonreciprocity of azimuthal spin wave modes in submicron vortex state disks
Sali Salama, Joo-Von Kim, Abdelmadjid Anane +1
Vortex states in thin film disks host spin-wave modes that are geometrically quantized according to their radial and azimuthal indices. Previous studies have shown that hybridizati…
