So it sounds like the purple crystal isn't repelled by magnets. So what part of the samples was causing the magnetic properties? Or are we saying that all of those videos and images were faked?
- flatline 3y agoSays it right there: CuS. You should read the whole thing, it’s really well-written and thorough.
- floxy 3y agoThe Cu₂S was responsible for the temperature dependent resistivity measurement caused by a phase change at 104 °C, not the magnet properties. If you have some more information on the ferromagnetic properties of copper sulfides, I'd like to learn more.
