How to plot magnon band structure with vasp

In this section we show an application of calculating the magnon band structure using the TB2J results.

There is a script within the TB2J package: TB2J_magnon.py, which can be used to plot the magnon band structure. We can show its usage by:

TB2J_magnon.py --help

usage: TB2J_magnon.py [-h] [--fname FNAME] [--qpath QPATH]  [--figfname FIGFNAME] [--show]

TB2J_magnon: Plot magnon band structure from the TB2J magnetic interaction parameters

optional arguments:
  -h, --help     show this help message and exit
  --fname FNAME  exchange xml file name. default: exchange.xml
  --qpath QPATH  The names of special q-points. If not given, the path will be automatically choosen. See https://wiki.fysik.dtu.dk/ase/ase/dft/kpoints.html for the table of special kpoints and the default path.
  --figfname FIGFNAME  The file name of the figure. It should be e.g. png, pdf or other types of files which could be generated by matplotlib.
  --show         whether to show magnon band structure.

The input file specified to the –fname parameter is by default exchange.xml file, which is the output in the Multibinit xml format, as can be found in the TB2J_results/Multibinit directory.

Here we take the BCC Fe as an example. After we have the TB2J_results directory, we can go to the Multibinit directory and find the exchange.xml file. The q-path can be generated automatically from the atomic structure information, using the [ASE][https://wiki.fysik.dtu.dk/ase/ase] library. We need to specify a path of q-points if the default is not what we want. The default k-path and the labels of the special kpoints can be found at this page. For example, we want a path of “Gamma-N-P-Gamma-H-N” instead of the default, it can be given by:

TB2J_magnon.py --qpath GNPGHN --figfname magnon.png --show

The magnon band structure is then written to a By using the –show parameter, the band structure is shown on screen.

I have tried to make video in a way that ordinary people who are not familiar with quantum espresso can understand in common language, i am sorry if there is. (for publ，lab 11: how to draw electronic band structure without any external software?，lab 3.1 : write input scf file for quantum espresso using windows (beginner leve，lab 4.1: convergence of kinetic energy cut off (ecutwfc) in quantum espresso.，lab 5 relax and vc relax (optimization of atomic positions and cell parameters)，lab 7. To understand how band structure changes relative to the fermi level in real space, a band structure plot is often first simplified in the form of a band diagram. in a band diagram the vertical axis is energy while the horizontal axis represents real space. horizontal lines represent energy levels, while blocks represent energy bands. And choose ’tools’ ! ‘bulk modulus’. this will produce a fit of the energy vs. unit cell volume for the five calculations, the bulk modulus b and equilibrium volume v0 can be read from the plot title. be sure to calculate the equilibrium lattice constant a from v0 as we will use it for all subsequent calculations on silicon. 3. calculate the energy band gap for doped si, 4. understand how temperature dependent measurements are a major experimental tech nique, 5. calculate the temperature dependent coﬃt of the majority carriers and 6. through experimental realizations, appreciate a physical understanding of the band gap structure of semiconductors. references.

Calculation of the bandstructure for si within dft hf. the bandstructure in vasp can be obtained following three different procedures. the standard procedure (procedure 1), applicable at pbe level, is also described in fcc si bandstructure example . within hybrid functional theory it is possible to plot bandstructure using procedure 2 or 3. For band structure calculation or energy k calculation you should follow a general procedure more than a unique equation: 1. first, the hamiltonian h of the periodic structure should be the input. It then plots the resulting band structure and save it as band . $ pyband. the default output image name can be changed by adding o yourimagename.suffix to the above command line. note that the image format is automatically recognized by the script, which can be any format that is supported by matplotlib.
