Modified LAMMPS parameter files for the Co-Fe, V-Fe, and V + Cantor system

Binary parameters of the Co-Fe and V-Fe systems are revised based on the "Won-Mi Choi et al., CALPHAD 74 (2021) 102317".
The details of the modification are attached by ppt file, and modified binary LAMMPS parameters of the Co-Fe and V-Fe system are attached. 
Ternary parameters of Co-Fe or V-Fe containing systems also need to be changed due to modification of binary parameters. 
Therefore, the modified LAMMPS parameter of the V + Cantor system is also attached.
