English to Greek Science Science (general)

"A part of my research was on semiconducting Fe3O4 materials; I used neutronography, static magnetic, electric, and magnetoresistance measurements to describe their properties."


The main subject is about nanotechnology and nanostructures. I have searched everywhere and couldn't find the Greek definition of this term or, at least, a close term of neutronography.
I tried many combinations and searched them on Google and Greek dictionaries to see if they exist and no luck on that part either.

Thank you in advance.
