abstract = {Static strain in complex oxide heterostructures has been
extensively used to engineer electronic and magnetic
properties at equilibrium. In the same spirit, deformations
of the crystal lattice with light may be used to achieve
functional control across heterointerfaces dynamically.
Here, by exciting large-amplitude infrared-active vibrations
in a LaAlO$_3$ substrate we induce magnetic order melting in
a NdNiO$_3$ film across a heterointerface. Femtosecond
resonant soft X-ray diffraction is used to determine the
spatiotemporal evolution of the magnetic disordering. We
observe a magnetic melt front that propagates from the
substrate interface into the film, at a speed that suggests
electronically driven motion. Light control and ultrafast
phase front propagation at heterointerfaces may lead to new
opportunities in optomagnetism, for example by driving
domain wall motion to transport information across suitably
designed devices},
