We studied the dependence of exchange bias on the annealing temperature for different MnN thicknesses in detail and found that samples with $t_{\\text{MnN}}>32\\,$nm show an increase of exchange bias for annealing temperatures higher than $T_{\\text{A}}=400\\,^{\\circ}$C. Maximum exchange bias values exceeding $2000\\,$Oe with reasonably small coercive fields around $600\\,$Oe are achieved for $t_{\\text{MnN}}= 42, 48\\,$nm.
