abstract = {All-oxide-based synthetic antiferromagnets (SAFs) are
attracting intense research interest due to their superior
tunability and great potentials for antiferromagnetic
spintronic devices. In this work, using the
La2/3Ca1/3MnO3/CaRu1/2Ti1/2O3 (LCMO/CRTO) superlattice as a
model SAF, we investigated the layer-resolved magnetic
reversal mechanism by polarized neutron reflectivity. We
found that the reversal of LCMO layer moments is mediated by
nucleation, expansion, and shrinkage of a magnetic soliton.
This unique magnetic reversal process creates a reversed
magnetic configuration of the SAF after a simple field
cycling. Therefore, it can enable vertical data transfer
from the bottom to the top of the superlattice. The physical
origin of this intriguing magnetic reversal process could be
attributed to the cooperation of the surface spin-flop
effect and enhanced uniaxial magnetic anisotropy of the
bottom LCMO layer. This work may pave a way to utilize
all-oxide-based SAFs for three-dimensional spintronic
devices with vertical data transfer and high-density data
storage.},
