Paramagnetic susceptibility of BCC ferrite (a-Fe) and of cementite (Fe3C), was
calculated in a temperature range above
the Curie point, using a density functional-based method in conjunction with statistical
approximations. The electronic
structure and the magnetic energy of both systems were calculated using the full
potential linear augmented plane wave
(FPLAPW) method as implemented in the Wien2k Code. The temperature effect was
captured by introducing the
Boltzmann statistical distribution to describe the orientation
