Plots a user-specified number of the lowest energy levels of the system as a function of the applied magnetic field. The energies are obtained using the Arnoldi method.
Syntax
fieldscan_enlev(spin_system,parameters)
Arguments
parameters.fields - two-element vector in Tesla,
ordered as [from to]
parameters.npoints - number of points in the scan
parameters.orientation - system orientation, three-
element vector containing
Euler angles in radians,
ordered as [alp bet gam]
parameters.nstates - number of lowest energy states
to solve for
Outputs
This function plots a graph.
Examples
See quartet_levels.m, triple_dy_levels.m, and dy_lft_single_2.m files in examples/giant_spin directory.
Notes
The function runs in parallel over the values of the applied magnetic field. The sys.magnet parameter is used for internal normalisation and must be set to exactly 1 Tesla.
