abstract = {The intermetallic compound MnFe4Si3 has been studied by
high-resolution Time of Flight (TOF) neutron powder
diffraction. MnFe4Si3 crystallizes in the hexagonal space
group P63/mcm with lattice constants of a=b=6.8043(4) Å and
c=4.7254(2) Å at 310 K. Magnetic susceptibility
measurements show clearly the magnetic transition from
paramagnetism to ferromagnetism at about 302(2) K. Magnetic
structure refinements based on neutron powder diffraction
data with and without external magnetic field reveal strong
evidence on the origin of the large magnetocaloric effect
(MCE) in this material as a partial reordering of the spins
between ~270 K and 300 K. In addition, electronic structure
calculations using the self-consistent, spin-polarized Tight
Binding-Linear MuffinTin Orbital (TB-LMTO) method were also
accomplished to address the “coloring problem” (Mn/Fe
site preference) as well as the unique ferromagnetic
behavior of this intermetallic compound.},
