It is not clear to me that what did you mean by research projects? Did you mean, research paper or research grants? However, you can get a good solid idea about the field of ferrites and ferroelectrics from the below links.
It always depends on the level e.g. for PhD, post-doc or big grants. But the common thing is the originality means you should have your own idea that may also based on previous work but something new. You should also try to focus on significance, multidisciplinary, and link to industry if possible. Hope if may help you.
