Modulated Scanning Calorimetry shows the non-reversing heat flow
near to display a sharply defined global minimum in
the 0.28 < x < 0.40 range, identified with the self-organized
phase (SOP) of titled glasses.
NMR, Raman
scattering and constraint counting algorithms suggest this phase
to consist of two distinct global morphologies; a
-rich
backbone that has a dimensionality 2< d< 3, and P-rich ribbons
that have
. The ribbons dominate the physical
behavior of stressed rigid (0.40 < x < 0.50) glasses with
unusual consequences.
