Magnetodielectric detection of magnetic quadrupole order in Ba(TiO)Cu4(PO4)4 with Cu4O12 square cupolas
Abstract
Experimental knowledge of magnetoelectric (ME) activity from magnetic multipole moments has so far been limited. Here, Kimura et al. show that a magnetic square cupola cluster such as Cu4O12 realized in Ba(TiO)Cu4(PO4)4is a promising structural unit carrying ME-active magnetic quadrupole moments.
