It turns out that there is ferromagnetic correlation between two triangular nets in a W layer and there is very weak antiferromagnetic correlation between

A second mode, seen by Raman [17] at lower energies, is also observed in the INS data, but only in a limited range of the Brillouin Zone, from q = (0.07, 0, 0), where it intercepts
