Row vector that contains integers, each integer
assignes one of the matrices from the spinw.matrix property
to a magnetic atom in the generated spinw.matom list as a single
ion anisotropy. Zero value of aniso means no single ion
anisotropy for the corresponding magnetic atom.

g

Row vector with integers, each integer
assignes one of the matrices from the spinw.matrix property
to a magnetic atom in the spinw.matom list as a
g-tensor. Zero value of g means a default g-value of 2 for
the corresponding atoms.

field

External magnetic field stored in a row vector with 3 elements,
unit is defined in spinw.unit (default unit is Tesla).

T

Temperature, scalar, unit is defined in spinw.unit (default
unit is Kelvin).
