Web29 jul. 2024 · MnBi is remarkable for having a magnetocrystalline anisotropy (MCA) that increases with temperature. This unusual behavior has been attributed to the thermal expansion of the lattice and, more recently, to an anisotropic vibrational free energy. However, the effect of magnetic fluctuations on the MCA has not yet been quantified. … Web26 jan. 2015 · A good starting point, if you are unsure what smearing to use for relaxations, is usually Gaussian smearing (ismear 0) with a small sigma value (0.05, 0.1), the sigma value should be tested and in ...
