Unnatural look for nickel Physicists have made a form of nickel that does not exist in nature. Xiaofeng Jin of Fudan University in Shanghai and colleagues in China, Italy and the US have made nickel with a body-centred cubic structure and shown that it is ferromagnetic. However, its magnetic properties are completely different from those of the naturally occurring phase, which has a face-centred cubic structure (C S Tian et al. 2005 Phys. Rev. Lett. 94 137210).
