• is used. This approach includes methods of first principles, spin models based on the stochastic Landau–Lifshitz–Gilbert equation, and a submodel of micromagnetism, described by the Landau–Lifshitz–Bloch equation. The reference [32] is also devoted to the development of modeling methods in the field

Here, these functions have been rescaled to fit the properties of GdFe. To do so, one needs to know the Curie temperature, the saturation magnetisation, the uniaxial

• predictions for the “magnetic management” in magnetic memory cells on a picosecond timescale based on the use of the Landau–Lifshitz–Gilbert equation [38][39][40]. Indeed, in a well-known classical macro-spin approximation, one can arrive at the formula for the component of magnetization dynamics, M, in a

• form equivalent to that obtained above for a quantum system. The Landau–Lifshitz–Gilbert equation can be written as follows: where γ is the gyromagnetic ratio, M(t = tin) = {0, 0, M}, and M(t = trev) = {0, 0, −M}. The magnetic field is given in the form H(t) = nXH(t) + nZHZ, where HZ > 0 is a constant
