The merger of a binary neutron star system is suggested as the central engine
of short gamma-ray bursts (sGRBs). For the merger process, simulations predict
that magnetic field is amplified beyond magnetar field strength by
Kelvin-Helmholtz instabilities. With the Large Area Telescope (LAT), bursts
have been detected that show a temporally extended component in coincidence
with a short-lasting peak at the end of the prompt phase. We show that the
presence of these LAT components in a sGRB could provide evidence of magnetic
field amplification in the neutron star merger.
