TEM研究揭示了晶体MnVO中磁畴结构的温度依赖性，这引起了相当大的关注，因为有趣的耦合的结构顺序（磁性，轨道和晶格）和这些现象的潜在应用。虽然这种晶体由于长程亚铁磁有序而形成了定义明确的磁畴，但在立方相和四方相中，在低于1042 K的温度下，磁性信息急剧减少。这些结果为理解磁异常提供了有用的信息，如热磁化曲线中的玻璃化行为，这在此温度范围内已被报道。
TEM studies have revealed the temperature dependence of the magnetic domain structure in the crystal MnVO, which has attracted considerable attention because of the intriguing coupling of structural orders (magnetism, orbital, and lattice) and potential applications of these phenomena. Although this crystal forms well-defined magnetic domains because of long-range ferrimagnetic order, in both the cubic and the tetragonal phases, the magnetic information is dramatically reduced at temperatures below ∼42 K. The results provide useful information for understanding magnetic anomalies, such as glassy behavior in the thermomagnetization curves, which have been reported in this temperature range.
