LDAUJ = [real array]
Default: LDAUJ = NTYP*0.0
Description: LDAUJ specifies the strength of the effective on-site exchange interactions.
Mind: one has to specify one number for each atomic species.
Warning: it is important to be aware of the fact that when using the L(S)DA+U, in general the total energy will depend on the parameters U and J (LDAUU and LDAUJ, respectively). It is therefore not meaningful to compare the total energies resulting from calculations with different U and/or J, or U-J in case of Dudarev's approach (LDAUTYPE=2).
