Protect files from the Domain Admin

Hello there,
I’m not experienced in Domain Admin.
Just wondering if there is any way to protect some files from being accessed by a Domain Admin if my machine is in that domain.
I can use the local admin account to create these files (so Administrator ownership) but my question is: can the Domain Admin take the ownership of those files? Then change the permissions and read/copy or access them in any way?

Is there any way to protect private documents from being accessed if the machine belong to a domain? [ADDED] maybe filesystem encryption? Is there any other way?

Thanks!
