More details: The bulk magnetic behaviors of the pyrochlores Yb2V2O7 and Tm2V2O7 were investigated. Calculated susceptibilities were adjusted to obtain the best fit to experimental data. A cubic crystal field Hamiltonian was used with B??4 ��0.633 and B??6 .000705 K for Yb3+ and B??4 .0297 and B??6 .000339 K for Tm3+. The calculated susceptibility for Yb3+ was found to be insensitive to the addition of an axial B??2 parameter to the cubic Hamiltonian.
