The experimental realization of magnetic skyrmion crystals in centrosymmetric materials has been driven by theoretical understanding how a delicate balance anisotropy and frustration can stabilize topological spin structures applied fields. Recently, the material Gd_{2}PdSi_{3} was shown to host field-induced crystal, but stabilization mechanism remains unclear. Here, we employ neutron-scattering measurements on an isotopically enriched polycrystalline sample quantify interactions that drive...

In quantum magnets, magnetic moments fluctuate heavily and are strongly entangled with each other, a fundamental distinction from classical magnetism. Here, inelastic neutron scattering measurements, we probe the spin correlations of honeycomb lattice magnet YbCl3. A linear wave theory single Heisenberg interaction on lattice, including both transverse longitudinal channels response, reproduces all key features in spectrum. particular, identify Van Hove singularity, clearly observable sharp...

Doping rare-earth ions into spinel ferrites can alter their electrical and magnetic properties. The present study delineates the structure–property relationship of effect terbium doping in NiFe2O4 ferrite. X-ray diffraction analysis (XRD) showed unit cell lattice expansion with increased Tb3+ content. Fourier transform infrared spectroscopy (FTIR) results indicate preferential occupancy at octahedral B site. parameters derived from room temperature hysteresis loops where both saturation...

Ammonia is a promising candidate as liquid hydrogen energy storage medium, but it requires catalytic decomposition (ammonia cracking) to regenerate hydrogen. Recently developed trimetallic ruthenium-potassium-promoter (RuKM) ammonia catalysts have exceptionally low temperatures, able perform the 250 °C, which significantly lower than other known that require temperatures above 500 °C. However, effects of RuKM precursor on activity not been investigated. We report observed differences 3%...
