Query: Neutron scattering investigation of magnetic bilayer correlations in
  $La_{1.2}Sr_{1.8}Mn_2O_7$   Neutron scattering investigations of the paramagnetic correlations in the
layered manganite La$_{1.2}$Sr$_{1.8}$Mn$_{2}$O$_{7}$, which exhibits colossal
magnetoresistance above the Curie transition at T$_C$ = 112 K, show that spins
in neighboring layers within each bilayer are strongly canted at an average
angle that is dependent on both the magnetic field and temperature, as
predicted by de Gennes. The in-plane correlation length does not diverge at
T$_C$, although the magnetic Bragg intensity obeys critical scaling below
T$_C$, with the same temperature dependence as the zero-field electrical
conductance.
