Hello,
This is not a cannulart, I find that it can be giant and finally lead to a "perpetual movement", to reflect on:

This is not because we always said that it is impossible that we should not try

Magnetic cold is not a recent discovery ...
Discovered in 1881 by Warburg and explained theoretically and named "low-calorie effect" 1918 by Weiss and Picard.
Nevertheless, numerous researches have had him since 2000 on the question.

Hello
It seems interesting because some materials have their Curie temperature (T ° or this effect is remarkable) in use temperatures I would say "domestic":
http://fr.wikipedia.org/wiki/Gadolinium
Other info:

Who talks about nickel and spontaneous magnetic fields near its Curie temperature, does that mean anything to you?
This system seems to have been the subject of intense and (sometimes) confidential research because it would seem to consume - + 30% less energy than gas compression refrigeration:

Hello,
To buy gadolinium
http://www.stanfordmaterials.com/gd.html
But the price is not online, you have to call for a tender.
(Found, around 4000 € per kilo !!)
