Un nouveau corps magneto-electrique: LiMnPO4

Multi-step-like Magnetization of LiNiPO4 in a Pulse Magnetic Field

“…The lithium orthophosphate of nickel belongs to olivine family of orthorhombic antiferromagnets with general formula LiMPO 4 (where M = Ni 2+ , Co 2+ , Fe 2+ , Mn 2+ ) which are known to be magnetoelectrics [1][2][3][4]. At the antiferromagnetic (AFM) ordering the unit cell contains four magnetic ions [5].…”

The Second Order Magnetoelectric Effect in Yttrium Iron Garnet

“…Dzyaloshinskii (1959) reasoned, from the effect of symmetry operators on the free energy of the crystal, that the magnetoelectric effect should be present in materials which have combined space and time inversions as symmetry elements of their magnetic point groups. He noted that chromium oxide was such a material and predicted that the magnetoelectric effect should be present, a prediction that was confirmed experimentally by Astrov (1960) and since then the effect has been observed in a number of materials (Al'shin and Astrov (1963), Rado (1964Rado ( , 1969, Ascher et al (1966), Mercier et al (1967aMercier et al ( , 1967bMercier et al ( , 1968aMercier et al ( , 1968b). …”

Dielectric relaxation and ionic conductivity studies of LiCaPO4

“…Since 1965, the LiMPO 4 (M = Mn, Co, Ni, Fe) compounds have attracted more attention because of their interesting magneto-electric properties [1][2][3][4][5][6][7][8][9][10]. Santoro et al reported the magnetic properties of the polycrystalline LiNiPO 4 and LiCoPO 4 phases for the first time [11,12].…”
