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 with 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. PACS Nos.: 75.10Nr, 75.50Ee, 75.50Lk

In the present work, the magnetic properties of high-Tc Bi 1.7 Pb 0.3 Sr 2 Ca 2-x Sm x Cu 3 O 12 system (x = 0.03) have been investigated, for different temperatures below Tc. Substitution of Sm 3+ for Ca 2+ is found to change the superconducting properties of the system, despite the weak paramagnetic nature of the Sm 3+ ion. The dc magnetization measurements performed on the compound reveal that the superconducting regions decrease with increasing temperature and magnetic field. The results are explained on the basis of a possible reduction of hole concentration with trivalent rare-earth ion substitution, and also on the basis of the magnetic nature of the substituted Sm 3+ ions.
