Notes:
Six inequivalent Cu2+ EPR spectra were observed at 4.2 K in single crystals of FeSiF6 ⋅ 6H20. The estimated parameters gz∼2.38 and θ∼40°, where θ is the angle between the ionic z axis and the c axis, differ from those measured in crystals of similar structure. These differences have been explained in terms of an isotropic Cu2+–Fe2+ exchange Hamiltonian JS1 ⋅ S2, with J=+(0.030±0.003) cm−1, which gives a contribution gex∼−5.05 J sin2 θ, where θ is the angle between the external magnetic field and the z axis. Perpendicular to the c axis, an independent estimate of +0.034 cm−1 for J was made from the low-field displacement of a satellite spectrum.
