<br>
Pseudopotential of Mn you use has s and p semicore states in valence.<br>
<br>
A brief check of the articles you have attached shows that U_{Fe}<br>
parameters are slightly different (U_Fe = 5eV in Li et al and U_Fe = 4.5<br>
eV ).<br>
<br>
Li et al used VASP and PAW pseudos from VASP library, while H. Lee et al<br>
used QE and ultrasoft pseudos. In your place, I would try to use the same<br>
paratameters as H. Lee and to reproduce their results.<br>
<br>
