A double-spiral spin ordering in the helimagnet YBaCuFeO
Yu-Hui Liang, Chun-Hao Lai, Chin-Wei Wang +9
Materials with a spiral spin ordering always show a rich phase diagram and can be a playground for studying the exotic physical properties associated with spiral magnetism. Using n…
Thermal Nanoquakes: Terahertz Frequency Surface Rayleigh Waves in Diamond Nanocrystals
Caleb Stamper, Matteo Baggioli, Pablo Galaviz +8
Mechanical THz vibrations in nanocrystals have recently been harnessed for quantum sensing and thermal management. The free boundaries of nanocrystals introduce new surface wave so…

L. Heinze, T. Kotte, R. Rausch +13
We report an extensive high-field study of atacamite CuCl(OH), a material realization of quantum sawtooth chains with weak interchain couplings, in continuous and pulsed ma…
Dynamic Nanodomains Dictate Macroscopic Properties in Lead Halide Perovskites
Milos Dubajic, James R. Neilson, Johan Klarbring +26
Empirical A-site cation substitution has advanced the stability and efficiency of hybrid organic-inorganic lead halide perovskites solar cells and the functionality of X-ray detect…
Understanding spin currents from magnon dispersion and polarization: Spin-Seebeck effect and neutron scattering study on Tb3Fe5O12
Y. Kawamoto, T. Kikkawa, M. Kawamata +9
Magnon spin currents in the ferrimagnetic garnet Tb3Fe5O12 with 4f electrons were examined through the spin-Seebeck effect and neutron scattering measurements. The compound shows a…
