Origin of the Giant Negative Thermal Expansion in Mn3(Cu0.5Ge0.5)N
The giant negative thermal expansion in the Ge-doped antiperovskite Mn3CuN compound is theoretically studied by using the first principles calculations. We propose that such a negative thermal expansion property is essentially attributed to the magnetic phase transition, rather than to the lattice v...
