Abstract
We have studied the magnetic properties of thin inhomogeneous Ni films in the vicinity of a percolating threshold. A detailed analysis of th e extraordinary Hall effect as a function of temperature gives quantit ative information on the variation of the magnetic order. We show that the Hall effect is related to the magnetic properties at the grain sc ale. The strength of the magnetic coupling is insensitive to the him m orphology. The magnetic behavior is similar to that of homogeneous thi n films.
