# ICHIBARE

From Vaspwiki

**ICHIBARE** = 1 | 2 | 3

Default: **ICHIBARE** = 1

Description: determines the order of the finite difference stencil used to calculate the magnetic susceptibility.

**ICHIBARE** specifies the order of the finite difference stencil used to calculate the magnetic susceptibility (second order derivative in Eq. 47 of Yates *et al.*^{[1]}). **ICHIBARE** may be set to 1, 2, or 3. Often the default (**ICHIBARE**=1) is sufficient. A higher **ICHIBARE** results in a substantial increase of the computational load.
