Main Question or Discussion Point

I wonder if the process of magnetisation of ferromagnetic material is reversible in
a thermodynamic sense according to the following definition of reversibility?

Reversible process - let's assume that initial state of the system
was a, initial state of the environment was b and final state of the system and
environment was a' and b' appropriately. If there exists a process which
changes the state of full system (considered system + environment)
form (a',b') to (a,b) the process is said to be reversible.
(This definition allows the reverse process to completly different then the one
which change the state of the system.)

What are your opinions about it?

If you heat it up hot enough you will reach the curie temp.
