In this work, structural, electronic and magnetics properties of EuMnPF were investigated using density functional theory within the Perdew-Burke-Ernzerhof generalized gradient approximation (PBE-GGA)¹ of the exchange-correlation energy implemented, in the Vienna ab-initio simulation package (VASP)².

The optimized lattice parameters and bulk modulus of the parent compound are determined by fitting a set of data points to the Birsh-Murnaghan equation of state and compared with experimental data³ using GGA ,vdW-DF,rev-vdW-DF2 and vdW-SCAN+rVV10 methods.

The vdW-SCAN+rVV10 density can predict perfectly the lattice parameters which are in excellent agreement with experimental value.

The magnetic behavior of the compound are clearly shown from partial density figures.
