WebLong-range order is the tendency for moments to align for large distances. For temperatures a few degrees below T c the moments have strong short-range order but only a small amount of long-range order, so the bar is not very magnetic. The tendency for long-range order increases at lower temperature. The Curie temperature is the point … Web18 de fev. de 2003 · The short-range ordered structure is interpreted as being formed as a result of competition between the X-point ordering tendency and the L-point ordering …

These changes have been known to induce long-range positive shifts (between +30 and +150 mV) in the redox potential of the primary … WebLong-range order permits rows of atoms to span the image and maintains agreement of row orientations. Ordinary crystal structures, such as that of Figure 1 , display long-range order. Strict rules govern the relative placement of atoms at remote locations in solids with long-range order.
