  Topological superconductivity has been sought for in a variety of
heterostructure systems, the interest being that a material displaying such a
phenomenon could prove to be the ideal platform to support Majorana fermions,
which in turn could be the basis for advanced qubit technologies. Recently the
high Tc family of superconductors, $FeSe_{x}Te_{1-x}$, have been shown to
exhibit the property of topological superconductivity and further, evidence has
been found for the presence of Majorana fermions. We have studied the interplay
of topology, magnetism and superconductivity in the $FeSe_{x}Te_{1-x}$ family
using high-resolution laser-based photoemission. At the bulk superconducting
transition, a gap opens at the chemical potential as expected. However, a
second gap is observed to open at the Dirac point in the topological surface
state. The associated mass acquisition in the topological state points to
time-reversal symmetry breaking, probably associated with the formation of
ferromagnetism in the surface layer. The presence of intrinsic ferromagnetism
combined with strong spin-orbit coupling provides an ideal platform for a range
of exotic topological phenomena.
