Structure and magnetic properties of LiNi1-xCoxPO4 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. © Published under licence by IOP Publishing Ltd.
