项目摘要
The objectives of this research are to explore magnetic phase transitions in novel pure, dilute and mixed magnetic insulators. The study of spin glass behavior in insulating materials are conducted. Also, several mixed magnetic systems are studied in which spin glass phases might occur. In other mixed magnetic systems tetracritical or other multicritical points in the magnetic phase diagram are investigated. As an example of a rare magnetic model class, a dilute magnetic system is studied as well. Variable temperature, variable field magnetization and susceptibility measurements are conducted on single crystal and polycrystalline samples. These studies are important because they provide information on areas such as zero-field splittings, ferromagnetic interactions, and spin class character.
本研究的目的是探索磁相位 在新的纯,稀磁和混合磁绝缘体的转变。 绝缘材料中自旋玻璃行为的研究 进行。 此外,还研究了几种混合磁系统, 可能出现自旋玻璃相。 在其他混合磁性 系统的四临界点或其他多临界点, 相图进行了研究。 作为一种罕见的磁性 模型类中,也研究了一个稀磁系统。 可变 温度、变场磁化强度和磁化率 测量在单晶和多晶上进行 样品 这些研究很重要,因为它们提供了 关于零场分裂、铁磁 交互和自旋类字符。
