Abstract: | Metastable ferromagnetic phases, for different compositions in La2MnCo1−xNixO6, are obtained for samples synthesized by a low-temperature method and annealed in air at different temperatures in the range 200-1350 °C. The Tcs of the ferromagnetic phases vary linearly between those of the phases of the end members. Tcs of the different phases of La2MnCo1−xNixO6 can be predicted based on the Tcs and spin states of Mn, Co and Ni in the different phases of the end members, La2MnCoO6 and La2MnNiO6. |
