All the compounds are spin-glass or cluster-glassphase below a certain temperature due to the competition between the antiferromagnetic and ferromagnetic correlations.
低温下始终出现自旋玻璃或团簇玻璃行为,说明存在反铁磁与铁磁的相互竞争。

In high temperature sintering , on the one hand, big across hole is formed by gas closed in porosity that passes through molten glassphase, and mechanical properties is declined.
