Betreff: [Wien] True half métal and false half métal

Hello sir, I have a questions to ask you
1-I have a Heusler alloy when I calculated the band structure I find that the 
energetic gap exceeds or touches the conduction band of the fermi levels in 
(spin dn) direction
My question, is this compound is a half metal or metal
2-how I can distinguish a real half metal and false half metal
3-I have another compound when I applied the GGA approximation I did not find a 
gap at the level of fermi but I applied the MBJ (GGA) the gap appears
My question is what I consider that this compound is metal or half metal
I will wait for your reply
