New Magnetic-Field-Sensitive Alloy Could Find Use in Novel Micromechanical Devices (image) National Institute of Standards and Technology (NIST) Share Print E-Mail Caption This is a transmission electron microscope image taken at NIST of an annealed cobalt iron alloy. The high magnetostriction seen in this alloy is due to the two-phase iron-rich (shaded blue) and cobalt-rich (shaded red) structure and the nanoscale segregation.
