Query: Magnetic avalanche of non-oxide conductive domain walls   Atomically sharp domain walls (DWs) in ferroelectrics are considered as an
ideal platform to realize easy-to-reconfigure nanoelectronic building blocks,
created, manipulated and erased by external fields. However, conductive DWs
have been exclusively observed in oxides, where DW mobility and conductivity is
largely influenced by stoichiometry and defects. In contrast, we here report on
conductive DWs in the non-oxide ferroelectric GaV$_4$S$_8$, where charge
carriers are provided intrinsically by multivalent V$_4$ molecular clusters. We
show that this new mechanism gives rise to DWs composed of nanoscale stripes
with alternating electron and hole conduction, unimaginable in oxides. By
exerting magnetic control on these segments we promote the mobile and
effectively 2D DWs into dominating the 3D conductance, triggering abrupt
conductance changes as large as eight orders of magnitude. The flexible
valency, as origin of these novel hybrid DWs with giant conductivity,
demonstrates that non-oxide ferroelectrics can be the source of novel phenomena
beyond the realm of oxide electronics.
