Query: Evidence for current-induced phase coexistence in Ca$_{2}$RuO$_{4}$ and
  its influence on magnetic order   Combining quasistatic and time-resolved transport measurements with X-ray and
neutron diffraction experiments we study the non-equilibrium states that arise
in pure and in Ti substituted Ca$_2$RuO$_4$ under the application of current
densities. Time-resolved studies of the current-induced switching find a slow
conductance relaxation that can be identified with heating and a fast one that
unambiguously proves an intrinsic mechanism. The current-induced phase
transition leads to complex diffraction patterns. Separated Bragg reflections
that can be associated with the metallic and insulating phases by their lattice
parameters, indicate a real structure with phase coexistence that strongly
varies with temperature and current strength. A third contribution with a $c$
lattice constant in between those of metallic and insulating phases appears
upon cooling. At low current densities, this additional phase appears below
$\sim$100 K and is accompanied by a suppression of the antiferromagnetic order
that otherwise can coexist with current carrying states. A possible origin of
the intermediate phase is discussed.
