La2Ni0.75Co0.25O4.08 samples were scratched off from the cells and added to the gelatin capsules in mounted straw under an inert atmosphere between 6 -10 mg and attached to the sample holder of vibrating sample magnetometer for measuring the magnetization as a function of temperature and magnetic field in MPMS VSM SQUID, Quantum Design. The samples were examined in the DC mode in the temperature range of 300 K to 10 K at 1 T field. Field dependent measurements were recorded at 10 K in the range between -7 and 7 T 3 Results and Discussions 3.1 Structure and morphology of La2Ni0.75Co0.25O4.08 and its cathode composite La2Ni0.75Co0.25O4.08 (oxygen content determined via iodometric titration) was obtained as a phase-pure material (see Figure ). The lattice parameters were found to be a = 3.88125(4) Å, c = 12.57064(18) Å, Vf.u = 189.365(4) Å , and the unit cell volume is comparable to La2NiO4 (189.05 A³), which is expected from the similar radii of the different transition metals. (if Co and Ni ions are trivalent with very similar ionic radius rCo2+ = 0.65 Å, rCo3+ = 0.545 Å and rNi2+ = 0.69 Å, rNi3+ = 0.56 Å, both low spin).
