MedicalResearch.com: What is the background for this study? What are the main findings?
Response: From a view point of practical applications, superparamagnetism is usually highly desirable, because it can prevent the magnetic particles from irreversible aggregation and ensure an excellent dispersity once the applied magnetic field is removed.
Up to now, the largest size of reported superparamagnetic clusters is around several hundreds of nanometers, which are composed of numerous nanocrystals, and hence exhibiting polycrystalline nature. In this sense, how to realize well pronounced superparamagnetism in large-size single crystals is of great interest to the general public.
MedicalResearch.com: What should readers take away from your report?
Response: Our superparamagnetic Fe3O4 single crystal is synthesized by a facile hydrothermal procedure. It is in sub-millimeter size range, and its saturation magnetization (ca. 90 emu/g) bears striking similarities with that of the ferrimagnetic Fe3O4 bulk.
MedicalResearch.com: What recommendations do you have for future research as a result of this study?
Response: This finding will shed new light on the development of superparamagnetic bulk materials, which are seen as highly impossible before.
MedicalResearch.com: Thank you for your contribution to the MedicalResearch.com community.
