Above the Curie temperature, the material is paramagnetism so that magnetic moments are in a completely disordered state.
However, ferrofluids lose their magnetic properties at sufficiently high temperatures, known as the Curie temperature.
However, it has a Curie temperature of only 60 C, which limits its usability.
The point at which there is no magnetization anymore is called the Curie temperature.
It is a ferrimagnetic material with a Curie temperature of 550 K.
Superparamagnetism is different from this standard transition since it occurs below the Curie temperature of the material.
High permeability below the Curie temperature in the workpiece is useful.
The 1980s saw the development of rare earth magnets with high energy products but undesirably low Curie temperatures.
When a sample is cooled below the Curie temperature, for example, the equilibrium domain configuration simply appears.
At temperatures below the Curie temperature the substance may become ferromagnetic.
