We report on a search for second generation leptoquarks (LQ) produced in $p\bar{p}$ collisions at sqrt{s} = 1.8 TeV using the D0 detector at Fermilab. Second generation leptoquarks are assumed to be produced in pairs and to decay to either \mu or \nu and either a strange or a charm quark (q). Limits are placed on \sigma(p-pbar -> LQ-LQbar -> \mu\nu + jets) as a function of the mass of the leptoquark. For equal branching ratios to \mu q and \nu q, second generation scalar leptoquarks with a mass below 160 GeV/c^2, vector leptoquarks with anomalous minimal vector couplings with a mass below 240 GeV/c^2, and vector leptoquarks with Yang-Mills couplings with a mass below 290 GeV/c^2, are excluded at the 95% confidence level.
