  Magnetic monopoles are hypothetical particles that carry magnetic charge.
Depending on their velocity, different light production mechanisms exist to
facilitate detection. In this work, a previously unused light production
mechanism, luminescence of ice, is introduced. This light production mechanism
is nearly independent of the velocity of the incident magnetic monopole and
becomes the only viable light production mechanism in the low relativistic
regime (0.1-0.55c). An analysis in the low relativistic regime searching for
magnetic monopoles in seven years of IceCube data is presented. While no
magnetic monopole detection can be claimed, a new flux limit in the low
relativistic regime is presented, superseding the previous best flux limit by 2
orders of magnitude.
