Re: [QE-users] magnetic moment and absolute magnetization

Dear Pooja, The list of atomic charges and magnetizations takes into account the values from the spheres around the ions which do not fill the entire space. However, the values of total and absolute magnetization are integrals over the whole simulation cell. In your sparse cell (6.09 Å lattice

Dear Vishva, Change ibrav from 2 to 1. On the one hand, ibrav = 2 is a rhombohedron-shaped simulation cell, a primitive cell of the fcc structure. A rock-salt material contains 2 atoms in this cell. On the other hand, your ATOMIC_POSITIONS correspond to an 8-atom conventional cube-formed cell

Dear Abdul, starting_magnetization is the initial ratio of the number of polarized electrons to the total number of valence electrons for the respective atomic species. Therefore, it ranges from –1.0 (all spins down) through 0.0 (paired spins) to +1.0 (all spins up). It is used to construct

Hello, Because periodic boundary conditions are applied, it seems to me that all your first 16 atoms (and not only them) are in fact located on the same place because their coordinates differ (nearly exactly) by lattice vectors, what you were told also by the error message. Please note that we

Dear Stephen, Make sure that your pseudopotentials contain all the electrons responsible for the magnetization. For example, based on the file name, I guess your cerium PP lacks the f-electrons. Hope that helps Martin Matas Ph.D. student University of West Bohemia Pátek, Srpen 07, 2020

Dear Dominik and everyone, I just want to add the information that this problem of zinc chalcogenides was also recently reported by Flores, Moreira and Piotrowski in J. Phys. Chem. A 124 (2020) 3778–3785, doi.org/10.1021/acs.jpca.9b11415. Martin Matas Ph.D. student University of West Bohemia

Dear Joaquim, I believe cell_dofree='ibrav' should do the work. The ibrav choice is preserved in that case. Hope that helps. Martin Matas University of West Bohemia Pilsen, Czech Republic Pondělí, 1 Duben, 2019 17:27 CEST, Joaquim Jornet Somoza napsal: > Dear QuantumEspresso user, > >

Dear experts, I appreciate that many new ultrasoft pseudopotentials for rare earths by Andrea Dal Corso have recently appeared on QE homepage. I performed calculations with a 2-atom primitive cell of metal holmium using Ho.pbe-spdn-rrkjus_psl.1.0.0.UPF, with both ferromagnetic and
