I am confused. I am told that chrome is
antiferromagnetic. So, is chrome magnetic or not?
There are many different types of magnetic behavior -- ferromagnetism,
ferrimagnetism, antiferromagnetism, diamagnetism, paramagnetism. They are
all types of magnetism, but are all different. One way to think of
'magnetism' is like 'color'. Each of these different kinds of magnetism is
like a different 'color'. You may have a red object and blue object that
look very different, but they both are 'colored'.
It turns out elemental chromium has some quite funky and interesting
magnetic properties, probably beyond the scope of this forum. Different
oxides of chromium have different magnetic properties as well.
Hope this helps,
