Number 140 (Story #3), August 13, 1993 by Phillip F. Schewe and Ben Stein THE HIGHEST MAGNETIZATION FOR A MATERIAL , 2.8 tesla in a Fe16N2 compound, has been observed by scientists at Hitachi in Japan (H. Takahashi et al., J. Applied Physics, 15 May 1993). This value is to be compared with those for ferromagnetic elements: 2.15 for iron, 1.76 for cobalt, and 0.61 for nickel. Magnets made from the iron-nitrogen compound might be useful for motors or magnetic-recording devices. (Physics World, August 1993.)
