Figure 7
Calculated mPDF of the spin-ice ground-state configuration obeying the `two-in two-out' ice rules. The inset shows one possible ground state, with one spin arbitrarily taken to be at the origin (blue), and the first-, second- and third-nearest neighbors shown in red, green and purple, respectively. The red (green) lines with short (long) dashes show the O-P-A and O-A-P (O-P-P and O-A-A) chains described in the body of the text.  [article HTML]
