Query: Magnetic Susceptibility Study of the Heavy Rare Earth Stannate
  Pyrochlores   The series of magnetic rare earth pyrochlore stannates R2Sn2O7 (R = rare
earth, except Ce and Pm) have been investigated by powder susceptibility
measurements down to T =1.8 K. The results are compared to results for the
analogous titanate series, which are well-known frustrated magnets. Unlike the
titanates, the whole series can be formed in the cubic pyrochlore structure.
Possible experimental advantages of studying the stannates are discussed.
