It may be worth looking at the CRYSTAL17 tutorial on this.
http://tutorials.crystalsolutions.eu/tutorial.html?td=ts&tf=tutorial-ts_crystal#energytol
CRYSTAL does not use NEB but does suggest you use a high SCF tolerance 10-11H.
It may also be worth looking at their method.

The Wikipedia article on metalloids says it's the overlaping valence and
conduction bands that define semimetals in physics.
Following textbooks in chemistry could lead to confusion as many chemists still
use the term for elements that cannot be classified definitively as metals or
non-metals
In the paramagnetic state, as Prof. Blaha says, the atoms still have magnetic
moments but they are randomly oriented. This arises when the thermal energy is
sufficient to overcome the spin-spin coupling. I would expect a calculation on
Gd at 0K to give you a ferromagnetic state with very small s
There is some confusion here about types of paramagnetism.
If the spin-polarised and non-spin polarised results are the same, it merely
means that the spin up and spin down bands are at equal energies. Pt has no
unpaired spins so no magnetic moment. It could from the calculation be
diamagneti
I have been following this thread and I think there is some confusion.
1. On the thread it said that the experiment showed it was Pauli paramagnetic.
This is the type of magnetism displayed by some metals e.g. sodium which is
only apparent if you apply a magnetic field.
2. If you include spin i

Your calculations are probably fine.
Apologies for my previous posting but my point was partly that I think you said
the experimentalists claimed it was Pauli paramagnetic.
Pauli paramagnetism is not the type of paramagnetism that arises from unpaired
electrons on metal ions in, for example, t
cm3/mol is the unit of the molar susceptibility in the cgs system. Did you want
to convert it to the mass susceptibility in cm3/g? If so you need to divide by
the relative molecular mass.
Should you not use SI rather than cgs units?

If you want to study a pair of interstitial N atoms, you must add two N atoms,
not replace P. Or if you are replacing P by two interstitial N atoms, you
remove one P and add two N at new positions.
Interstitial means the atoms are not on lattice sites.

I don't know why it starts again, but I guess there will be a minimum with the
two atoms at the N2 distance as the N2 bond is very strong. You could start by
putting your N atoms farther apart.

There is no reason you should not do a calculation for monoclinic and triclinic
systems. Look at the error message you have. Then check the User Guide and
previous questions. Only after trying suggestions from there write to the
mailing list with details of your files and error message.

Try P21/c or space group 11, but be carefuk as it maybe a non-standard setting.

For NMR you need CASTEP at the moment but I believe there are plans to add this

You may want to study Mg-doped GaN as this would be a p-type semiconductor but
you certainly would not want to study antiferromagnetic coupling between Mg2+
ions as Prof. Blaha has pointed out.
However if you were interested in Mg-doped GaN you would probably want a low
level of dopant and hence
