Measurement of the Fundamental Properties of Fe-Ti Cubic Oxides

该项目涉及生产单晶体， Fe-Ti氧化物 必要的设备已经建成， 通过助熔剂生长法生产这种晶体， 产生了一些磁铁矿和赤铁矿晶体。 虽然不 然而，对于研究目的，这种晶体的生产是令人满意的 将是一个简单的问题， 控制生长环境的参数， 生产优质晶体。 甲壳会被用来 测量磁晶各向异性常数使用铁- 磁共振波谱（FMR）。 初步实验将 在室温下与磁铁矿接触， 把这些实验带到居里蓬特附近， 多种组合物。

This project involves the production of single crystals of Fe-Ti oxices. The necessary apparatus has been constructed for the production of such crystals by the flux growth method and some magnetite and hematite crystals have produced. While not yet satisfactory for research pupose, production of such crystals will be a straightforward mater of working with the various parameters that control the growth environment until good quality crystals are produced. The crustals will be used to measure the magnetocrystalline anisotropy constant using ferro- magnetic resonance spectroscopy (FMR). Initial experiments will be with magnetite at room temperature and to eventually extend these experiments to the vicinity of the Curie pont for a variety of compositions.
