  Treated beyond the single-mode approximation, Measurement-Induced-Nonlocality
(MIN) is investigated for both Dirac and Bosonic fields in non-inertial frames.
Two distinctly differences between the Dirac and Bosonic fields are: (i) the
MIN for Dirac fields persists for any acceleration, while the quantity for
Bosonic fields does decay to zero in the infinite acceleration limit; (ii) the
dynamic behaviors of the MIN for Dirac fields is quite different from the
Bosonic fields case. Besides, we also study the nonlocality for Dirac fields
and find that the MIN is more general than the quantum nonlocality related to
violation of Bell's inequalities. Meanwhile some discussions of geometric
discord are presented too.
