I do not know about such (successful) experiments conducted by people.
But certain frogs make it routinely all by themselves -
becoming frozen for the winter and waking healthy in the spring 
(sometimes even after several years). They have physiological
adaptation for that - among others, special substances 
in body cells preventing crystalization of ice (which would lead  
to disruption of cell structure). So, in theory it is not impossible.
If, and how, it is possible to make artificially with organisms
(like humans) which do not have such natural adaptations
is still an open question, though.
It requires, I am afraid, much deeper knowledge in 
molecular biology and great advances in biotechnology.
I personally believe it will be possible with advanced nanotechnology
(some 50+ yrs, to toss a careless prediction ;-).
