What does it mean "we are able to predict them as spintronic" ? There is nothing to predict a material as spintronic, maybe they are some ferromagnets, ferrimagnets, antiferromagnets, or otherspecial cases of magnetism that you can predict. If you like to predict something for ambient conditions

The Curie temperature can be roughly estimated from a comparison of the total energies of the ferromagnetic and the antiferromagnetic states. For a better way please check our book Felser/Fecher Spintronics: From materials to devices published by Springer and in particular the chapter by Kübler

About the Néel temperature, I know two main strategies: - If you know an analytical formula which relates TN with J values (J: magnetic exchange parameters of your system) then you can estimate TN from DFT  calculations. It will require the calculation of all the J's values of your system. Such
