gm_spherical3d

Syntax

[m, k, n, name, pname, limit] = gm_spherical3d(S0, x)

Description

[m, k, n, name, pname, limit] = gm_spherical3d(S0, x) generates magnetic structure from given parameters while constraining the length of the spin on each atom. The parametrization of the magnetic structure consists of 2 spherical coordinates $(\theta,\varphi)$ angles per magnetic atom. All angles are in radian.

Input Arguments

x

Input parameters in the following order: $[\theta_1, \varphi_1, ... , k_x, k_y, k_z, n_\theta, n_\varphi]$.

S0

Spin quantum number in a row vector $(S_1, S_2, ...)$ or scalar if all spins are equal.

Output Arguments

S

Matrix, containing the spin orientations with dimensions of $[3\times n_{magExt}]$. Every column contains the $(S_x S_y S_z)$ spin components of a magnetic atom in the $xyz$ coordinate system.

k

Magnetic ordering wavevector in rlu units in a row vector.

n

Normal vector around which the spins are rotating for non-zero propagation vector in a row vector.

name

String, storing the name of the function.

pname

Name of the input parameters in a cell: {'Phi1_rad', ...}.

limit

Limits on the input parameters in a matrix with dimensions of $[2\times n_{param}]$. Every column contains a lower and upper limit on the corresponding parameter.
