A search in Goggle on "variogram cauchy" returns, as a first hit, the
following R manual page:

This is not for gstat though. Package Random Fields seems to have a
variogram that can do what you want:

Hope this helps.

You can add the word 'R-sig-geo' to your queries in Google and you will 
be searching the list as well.
