“…Recently, compounds with kagome lattice have attracted lots of attentions for the unique electronic structure and magnetic frustration, [1,2] which provides an exciting platform to study rich quantum physics, such as quantum spin liquid, [3][4][5][6] nontrivial band topology [7][8][9] and superconductivity (SC). [10][11][12][13][14][15][16] One of the most exotic features in the electronic structure of the kagome lattice is the flat band with little dispersion in k space, which results from the destructive interference of electron wave functions.…”

We report the physical properties of ThRu$_3$Si$_2$ featured with distorted Ru kagome lattice. The combined experiments of resistivity, magnetization and specific heat reveal bulk superconductivity with $T_{\rm{c}}$ = 3.8 K. The specific heat jump and calculated electron-phonon coupling indicate a moderate coupled BCS superconductor. In comparison with LaRu$_3$Si$_2$, the calculated electronic structure in ThRu$_3$Si$_2$ shows an electron-doping effect with electron filling lifted from 100 meV below flat bands to 300 meV above it. This explains the lower superconducting transition temperature and weaker electron correlations observed in ThRu$_3$Si$_2$. Our work suggests the $T_{\rm{c}}$ and electronic correlations in kagome superconductor could have intimate connection with the flat bands.

“…To meet the increasing demand for smaller and more energy-efficient microwave devices, an alternative technology that surpasses current complementary metal-oxide-semiconductor technology is urgently needed. Magnetic nanostructures hold promising applications in magnonics and are rapidly developing as potential sources for devices that use spin waves (SWs) to transmit and process information [1][2][3].…”

The interaction between phonons and magnons is a rapidly developing area of research, particularly in the field of acoustic spintronics. To discuss this interaction, it is necessary to observe two different waves (acoustic and spin waves) with the same frequency and wavelength. In the Ni80Fe20/Au/Co/Au system deposited on a silicon substrate, we observe the interaction between spin waves and surface acoustic waves using Brillouin light scattering spectroscopy. As a result, we can selectively control (activate or deactivate) the magnetoelastic interaction between the fundamental spin wave mode and surface acoustic waves. This is achieved by adjusting the magnetostrictive layer thickness in the multilayer. We demonstrate that by adjusting the number of layers in a multilayer structure, it is possible to precisely control the dispersion of surface acoustic waves while having minimal impact on the fundamental spin wave mode.
