3 method to convert from ferro to parra ?

Efforts:
1st:
when magnetization remain constant and temperature increases then the magnet will convert from ferro to parra because its field strength decreases.
example:
the temperature of iron is 770k if it increases from 770k the iron will be converted to parra.

2nd:
when temperature is zero and magnetization increases to its maximum.
example: ?

Question:
3rd:
what is the third one?
how a magnet could be converted to parra with both magnetization and temperature involving ?

The third method could involve using an external magnetic field to manipulate the direction of the magnetic domains within the material. This can be achieved through techniques such as magnetic annealing or applying a pulsed magnetic field. By aligning the magnetic domains in a specific direction, the material can be converted from ferro to parra. Additionally, a combination of temperature and external magnetic field could also be used to induce the conversion, as temperature can affect the movement and alignment of the magnetic domains. Further research and experimentation would be needed to fully understand and utilize this method.
