The EFG is a quantity assigned to a particular nucleus and there is<br>
no total EFG defined for the unit cell. The EFG can be negative or<br>
positive. Maybe you should read more literature on EFG, e.g.,<br>

Dear Tran<br>
I guess the second value (like in :EFG001:Co1 EFG = 11.74814 *10**21 V / m**2 :EFG001:Co1 EFG = 11.74810 *10**21 V / m**2) is the correct value of EFG that is<br>
11.74810 *10**21 V / m**2 in this case. Actually, SCF converged after 25 cycles and for each atom 25 values of EFG printed. Am I right?<br>

Dear TranMany thanks for your prompt reply. I have completely understood how to compute MM.<div><div><br>
<br>
About EFG:<br>
I guess we can not write total EFG for the whole system, I mean only one value of EFG ? Am I right, as it is a related to every nucleus behavior<br>
against external EF?<br>
I used the functional WCGGA. How can we select the EFG value for each nucleus if it is repeating as in my case like<br>
<br>
:EFG001:Co1 EFG = 11.74814 *10**21 V / m**2<br>
:EFG001:Co1 EFG = 11.74810 *10**21 V / m**2<br>
:EFG002:Co2 EFG = 11.74791 *10**21 V / m**2<br>
:EFG002:Co2 EFG = 11.74777 *10**21 V / m**2<br>
:EFG003:Ba1 EFG = -15.19830 *10**21 V / m**2<br>
:EFG003:Ba1 EFG = -15.19828 *10**21 V / m**2<br>
Why are the values of EFG for Ba negative? I have run calculation for EFG of In using LDA and the out put is again repeating as<br>
<br>
:EFG001: EFG = -0.00432 *10**21 V / m**2<br>
:EFG001: EFG = 0.13141 *10**21 V / m**2<br>
:EFG001: EFG = 0.47071 *10**21 V / m**2<br>
:EFG001: EFG = 2.66825 *10**21 V / m**2<br>
:EFG001: EFG = 3.74518 *10**21 V / m**2<br>
:EFG001: EFG = 3.75462 *10**21 V / m**2<br>
:EFG001: EFG = 3.73242 *10**21 V / m**2<br>
<br>

Hi,<br>
<br>
:EFGn (n=001, 002, etc.) is the value of the EFG at the nucleus<br>
with index 1, 2, etc. as listed in case.struct (the integer next to "ATOM").<br>
I can see that the EFG is printed twice for each atom, which is<br>
the case when lapw0 is run twice per iterations like for hybrid<br>
functionals. Maybe you are running hybrid functionals?<br>
<br>
:MMIn is the spin magnetic moment inside the sphere surrounding nucleus<br>
with index n. :MMTOT is equal to<br>
<br>
:MMTOT = :MMI001*mult(001) + :MMI002*mult(002) + ... + :MMINT<br>
<br>
where mult(n) is the multiplicity of atom n ("MULT=" in case.struct)<br>

Dear Users<br>
I am supposed to compute Electric field gradient and Magnetic moment for Ba2CoSi2O7. The spin quantum numbers for Ba and Co are<br>
3/2 and 7/2 both definitely ><br>
1. SO their nuclear quadrupole will interact with EFG. I run the calculations as suggest in UG for In. After using the command<br>
grep :EFG *.scf I got many values<br>
(given below). It is confusing which value should be selected and for which atom Ba or Co.<br>
<br>
:EFG001: EFG = 11.74814 *10**21 V / m**2<br>
:EFG001: EFG = 11.74810 *10**21 V / m**2<br>
:EFG002: EFG = 11.74791 *10**21 V / m**2<br>
:EFG002: EFG = 11.74777 *10**21 V / m**2<br>
:EFG003: EFG = -15.19830 *10**21 V / m**2<br>
:EFG003: EFG = -15.19828 *10**21 V / m**2<br>
:EFG004: EFG = 7.27133 *10**21 V / m**2<br>
:EFG004: EFG = 7.27130 *10**21 V / m**2<br>
:EFG005: EFG = 9.02430 *10**21 V / m**2<br>
:EFG005: EFG = 9.02430 *10**21 V / m**2<br>
:EFG006: EFG = 9.76192 *10**21 V / m**2<br>
:EFG006: EFG = 9.76192 *10**21 V / m**2<br>
:EFG007: EFG = 9.37876 *10**21 V / m**2<br>
:EFG007: EFG = 9.37872 *10**21 V / m**2<br>
:EFG008: EFG = 9.37871 *10**21 V / m**2<br>
:EFG008: EFG = 9.37872 *10**21 V / m**2<br>
<br>
Also, am I right that the total local magnetic moment for Co and O will be simply obtained by adding for each site like for Co it<br>
comes to be 2.43 + 2.43 = 4.68<br>
and similarly for O?<br>
<br>
:MMINT: MAGNETIC MOMENT IN INTERSTITIAL = 0.46707<br>
<br>
:MMI001: MAGNETIC MOMENT IN SPHERE 1 (Co) = 2.42639<br>
<br>
:MMI002: MAGNETIC MOMENT IN SPHERE 2 (Co) = 2.42640<br>
<br>
:MMI005: MAGNETIC MOMENT IN SPHERE 5 (O) = 0.01014<br>
<br>
:MMI006: MAGNETIC MOMENT IN SPHERE 6 (O) = -0.00276<br>
<br>
:MMI007: MAGNETIC MOMENT IN SPHERE 7 (O) = 0.07897<br>
<br>
:MMI008: MAGNETIC MOMENT IN SPHERE 8 (O) = 0.07898<br>
<br>
:MMTOT: SPIN MAGNETIC MOMENT IN CELL = 6.00006<br>
