Structure and magnetic properties of LiNi_1-xCo_xPO₄ magnetoelectrics with x = (0, 0.1, and 0.2)

Abstract We present the magnetic properties of LiNi1-xCoxPO4 magnetoelectrics, with x = (0–0.2), and their analysis of concentration dependences. Samples have been synthesized by a glycerol-nitrate method. To refine crystal structure X-ray diffraction measurements were carried out. Magnetic measurements were performed at the external magnetic field of 500 Oe over the temperature range (2–300) K. The neutron powder diffraction patterns of LiNi0.9Co0.1PO4 were recorded over temperature interval from 4.4 K up to 25 K. The partial doping in the LiNi1-xCoxPO4 magnetoelectrics the Ni ions for Co ions leads to a narrowing of the temperature interval where the incommensurate phase is established.
