Toward a better understanding of the magnetocaloric effect: An experimental and theoretical study of MnFe4Si3.
Original language description
The intermetalliccompoundMnFe4Si3 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)? and c=4.7254(2) ? at 310K. 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 evidenceon the origin of the large magnetocaloric effect(MCE)in this material as a partial reordering of the spins between 270K and 300K. In addition, electronic structure calculations using the self-consistent, spin-polarized Tight Binding-Linear MuffinTin Orbital method were also accomplished to address the ?coloring problem (Mn/Fe site preference)as well as the unique ferromagnetic behavior of this intermetallic compound.
