Abstract

In this letter we present the results of the search for massive magnetic monopoles in the penetrating cosmic ray radiation using the various subdetectors of the MACRO apparatus, during the period 1989-1995. Flux limits are given for the β = v/c range 4 × 10-5 < β < 1; for 10-4 < β < 10-1 the limits are below the Parker bound, ∼ 10-15 cm-2s-1sr-1.
