Mayoh, Geetha Balakrishnan, Julie B. Staunton, Devashibhai Adroja, and Andrew T. Boothroyd We present an extensive x-ray and neutron scattering study of the structure and magnetic excitations of ${\mathrm{Nd}}_{2}{\mathrm{PdSi}}_{3}$, a sister compound of ${\mathrm{Gd}}_{2}{\mathrm{PdSi}}_{3}$ that was recently found to host a skyrmion lattice phase despite its centrosymmetric crystal str… [Phys.
