Search for magnetic monopoles with MACRO

Data from the complete MACRO detector have been used to search for magnetic monopoles (MMs) of all expected velocities. Scintillator, streamer tube (instrumented with specialized electronics) and nuclear track detectors have been used to search for signatures coming from MMs; the scintillator and nuclear track subdetectors were used also for searches for other rare particles (nuclearites, charged Q-balls). Based on no observation of such signals, we establish stringent flux limits, for MMs as slow as a few 10-5c
