- Crystal.mag_dipdip_energy(na, nb, nc, progress_bar=True)[source]#
Computes magnetic dipole-dipole energy.
\[E = -\frac{\mu_0}{4\pi}\sum_{i > j}\left(3(\vec{m_i} \cdot \vec{r_{ij}})(\vec{m_j} \cdot \vec{r_{ij}}) - (\vec{m_i}\cdot\vec{m_j})\right)\]- Parameters:
- naint

Crystal.a3.- progress_barbool, default True
Whether to show progressbar.
- Returns:
- energyfloat
Dipole-dipole energy in meV.
