Magnetism of Fe2P investigated by neutron experiments and band structure calculations

Magnetic and Transport Properties of (Fe1-xNix)2P in View of KKR-CPA Results

“…1 we see the concentration dependent total and atomic magnetic moment variations in (Fe 1 _ x Nix ) 2 P system. In pure Fe2P the local magnetic moment 2.33B on Fe(3g) is almost three times larger than the one 0.83B on Fe(3f) [5]. These values remain almost constant up to x = 0.5.…”

“…At present, we restrict our calculations to the case when x = y (no site preference in occupancy), which is not fully supported by neutron diffraction and Mössbauer studies [9]. The experimental crystal data determined for Fe2P system [5] were used in all computations for intermediate compositions. In Fig.…”

“…The T2D hexagonal systems (space group P62m), where T represent 3d (Mn, Fe, Co, Ni) or 4d (Ru, Rh) transition metal elements, and D are metalloids (Si, P, As), exhibit complex behaviour of some measured quantities. The structural, magnetic and transport properties were investigated by various experimental techniques (neutron diffraction measurements, Mössbauer effect, specific heat, electrical resistivity, magnetization measurements) [1,2], as well as by the (475) band theory methods [3][4][5]. In general, T2P compounds form solid solutions with the same crystal structure.…”

Magneto-elastic properties and electronic structure analysis of the (Fe1−Ni )2P system

“…A strong dilution of such small magnetic moments may be the reason why a magnetic ordering is not observed experimentally already for not so high Ni concentration. The peculiar feature of electronic structure of Fe 2 P already mentioned in previous works [16], comes from strong spin polarisation of electrons near E F . Thus we found a large DOS peak for spin-down electrons mainly due to spin-down d-Fe(3g), whereas a deep DOS valley for spin-up electrons.…”

Magnetocrystalline anisotropy and the magnetocaloric effect in Fe2P

“…4 Such distribution of Fe and P atoms in the crystal lattice creates two magnetic sublattices with different interactions as well as magnetic moments: Fe I and Fe II being the low and high moment sites, respectively, with a total moment of ∼2.9 μ B /f.u. 5,6 Below its Curie temperature (T C ), around 214 K, the moments are aligned in a ferromagnetic arrangement along the c axis. 7 At T C , a first-order magnetic phase transition to the paramagnetic state occurs.…”
