This may help, they give some explanations as to how they created a scale-free network in the appendix

Dietrich Stauffer, Adriano Sousa and Christian Schulze (2004) 

Discretized Opinion Dynamics of The Deffuant Model on Scale-Free Networks 

http://jasss.soc.surrey.ac.uk/7/3/7.html

they refer to their scale-free network as the BA network after Barabási and Albert

The most famous algorithm to create scale-free networks (rather: networks

with power law degree distribution) is the Preferential Attachment model

Hi

I want to use a scale free network to model the interaction

between these people.

I thought of scale free as a descriptive property of the network

after it forms, rather than a constructive term.  How will you

create it? Will people chooose to interact by some feature and then

the status gets broadcasted, so that some people end up with many

more contacts than others?

It is a descriptive property, but I'm fairly sure that there are

algorithms from the field of social network analysis that will

generate a (random) scale-free network; there certainly are such

algorithms for power-law and small-world networks.  Try a search on

"scale-free network algorithm"; it has a few results that look

promising.
