Magnetodielectric detection of magnetic quadrupole order in Ba(TiO)Cu $_{4}$ (PO $_{4}$ ) $_{4}$ with Cu $_{4}$ O $_{12}$ square cupolas

K. Kimura, P. Babkevich, M. Sera +12

In vortex-like spin arrangements, multiple spins can combine into emergent multipole moments. Such multipole moments have broken space-inversion and time-reversal symmetries, and c…
