So forgive my troll level of physics ignorance, i've only had physics until my senior year in high school. Nevertheless, I was so intrigued by CVD diamond growing when first i heard about it, that it got me thinking. Let's say you had a diamond disc of radius 5cm placed in you CVD chamber. And as you were depositing the methane gas which builds the lattice for the growing diamond, you sequentially (by first switching off the microwave source..or not) introduce all the chemical elements necessary to make a neodymium magnet. Making sure to deposit only about a 2-atom-thick layer of these neodymium magnet ingredients. However, the neo-magnet ingredients should be deposited within a smaller radius to the diamond disc, something like 4cm instead of the disc's 5cm. So that the next deposition of methane (with accompanying microwaves) at a radius equal to the disc, would essentially (and simultaneously) encase and cook the neo-magnet ingredients into a rudimentary neodymium block ready for magnetization, albeit it being 2 atoms thick. Once the second round of methane deposition is done, we continue to deposit the neo-magnet ingredients again, and so on. The result would be a diamond cylinder block that looks like a stack of CD's stacked on top of each other, since if you looked at the stack along its length, you'd be able to peer to the other side of the room. But look at the stack from the top, and you'd see nothing but the Musician's album cover/art. My thinking for depositing such ultrathin layers of neo ingredients was that the diamond lattice which has to form on top could grant the magnet lattice some of their immovable properties (being diamond after all) to prevent the the finished diamond from hopefully tolerating very high temperature, physical, and other forms of stress. Now that you have an idea of what i am getting at, i want you to imagine the CVD chamber being fitted with a powerful electromagnet that would induce and maintain polar orientation of the neodymium layer at select times during the entire CVD process. So regarding the placement of the electromagnet poles, perhaps the "North" pole could be just atop the Chamber, while the "South" pole is fit just below the chamber. It look like you pinching a AAA battery at its ends between your thumb and index finger. Now of course, this is probably flawed to humorous level, but what the heck. This is just an entertaining thought for times in the shower or when trying to fall asleep, but whatever you do after reading this, please think about what such a magnet infused diamond could be capable of. Cheers, and thanks for reading :)
Good sir very nice learning experience
Sir can we use oxygen gas for etching
what language was it ?

bruh
I like your patience to type this long comment.
