Abstract: | Summary To detect gravitational waves (GW) in a frequency range between 10 Hz and few kHz a ground-based antenna was designed by the
French-Italian collaboration VIRGO. The antenna is a 3 km long interferometer with special suspensions for the optical components,
planned to reduce the seismic noise in order to reach the low-frequency region. Results on the seismic isolation devices are
given together with some preliminary results on the use of permanent magnets on the VIRGO suspensions.
