Magnetic Susceptibilities, Crystal Field Stark Energies, And Hyperfine Behavior Of Sm3+ In Hexagonal Single Crystals Of Sm(Cf3so3)(3)Center Dot 9h(2)O

Single crystals of samarium trifluoromethanesulfonate (SmTFMS) were prepared from the slow evaporation of the aqueous solution of SmTFMS. The crystals are elongated along the symmetry axis c of the hexagonal crystal. At room temperature, the c axis of the crystal sets parallel with the applied magnetic field which indicates that the susceptibility parallel to the c axis (chi(parallel to)) is greater than the susceptibility perpendicular to the c axis (chi(perpendicular to)). chi(parallel to) and chi(perpendicular to) were measured from 300 down to 14 K. Magnetic anisotropy (Delta chi=chi(parallel to)-chi(perpendicular to)) obtained from the values of chi(parallel to) and chi(perpendicular to) was also checked by direct measurements of Delta chi and both these results agreed very well. A crossover between chi(parallel to) and chi(perpendicular to) has been observed at similar to 56 K i.e., below this temperature chi(parallel to)更多
