内容記述
内容記述 We have prepared a set of polycrystalline samples of PbPd1−𝑥−𝑦Fe𝑦Li𝑥O2 (𝑥=0, 0.01, 0.02, 0.03, and 0.04; 𝑦=0, 0.02, and 0.05) and have measured synchrotron x-ray diffraction and magnetization systematically. We have found high-temperature ferromagnetism in Fe- and Li-substituted samples and the largest magnetic moment of 0.023 𝜇𝐵 per formula unit in PbPd0.93Fe0.05Li0.02O2. The ferromagnetism survives at 700 K, and the Curie temperature will be far above 800 K. Although similar but controversial high-temperature ferromagnets have been reported in many thin-film samples thus far, the discovered ferromagnetism is macroscopic in the sense that bulk samples stick to a permanent magnet at room temperature. The Fe and Li dependence of the ferromagnetism is complicated, implying that the ferromagnetism is truly unconventional.
