The classical two-sublattice Landau–Lifshitz–Bloch equation for all temperatures
Micromagnetic modeling has proved itself as a widely used tool, complimentary in many respects to experimental measurements. The Landau–Lifshitz equation provides a basis for this modeling, especially where the dynamical behaviour is concerned. However, this approach is strictly valid only for zer...

| description |
Micromagnetic modeling has proved itself as a widely used tool, complimentary in many respects to experimental
measurements. The Landau–Lifshitz equation provides a basis for this modeling, especially where the
dynamical behaviour is concerned. However, this approach is strictly valid only for zero temperature and for
high temperatures must be replaced by a more thermodynamically consistent approach such as the the Landau–
Lifshitz–Bloch (LLB) equation. Here we review the recently derived LLB equation for two-sublattice systems
and extend its derivation for temperatures above the Curie temperature. We present comparison with many-body
atomistic simulations and show that this equation can describe the ultra-fast switching in ferrimagnets, observed
experimentally
