   Ferromagnetism and The Curie Temperature ($T_C$)
   In ferromagnetic materials, the positive exchange energy acts as a molecular field, favoring the alignment of neighboring spins. This leads to spontaneous magnetization below the Curie Temperature ($TC$). Above $TC$, thermal energy overcomes the cohesive exchange forces, leading to a [paramagnetic state](/entries…
