Query: Creation of a Chiral Bobber Lattice in Helimagnet-Multilayer
  Heterostructures   A chiral bobber is a localized three-dimensional magnetization configuration,
terminated by a singularity. Chiral bobbers coexist with magnetic skyrmions in
chiral magnets, lending themselves to new types of skyrmion-complementary bits
of information. However, the on-demand creation of bobbers, as well as their
direct observation remained elusive. Here, we introduce a new mechanism for
creating a stable chiral bobber lattice state via the proximity of two skyrmion
species with comparable size. This effect is experimentally demonstrated in a
Cu$_2$OSeO$_3$/[Ta/CoFeB/MgO]$_4$ heterostructure in which an exotic bobber
lattice state emerges in the phase diagram of Cu$_2$OSeO$_3$. To unambiguously
reveal the existence of the chiral bobber lattice state, we have developed a
novel characterization technique, magnetic truncation rod analysis, which is
based on resonant elastic x-ray scattering.
