Comment on Making my own bubble memory?
jaredj@infosec.pub 8 months agoSam Zeloof has made chips in his garage and posted a whole series about it on Youtube. He bought his silicon wafers, he didn’t grow them, and his machines do take up the whole garage - but he did the whole thing himself. Fascinating viewing IMO. I don’t know anything about where one would get these garnetty materials you mention, though.

So, I’m still doing research, but it seems like any ferrimagnetic thin film should work.
Rare earths would have been in lower demand at the time I think, and growing garnets is relatively easy. Similar synthetic crystals are common as lasing mediums now.
