摘要：
We have successfully grown single crystalline Sr3-xCaxRu2O7 with the range of 2.0 <= x <= 3.0 using the floating-zone method. All compounds show orthorhombic symmetry in this substitution range, but the difference between lattice constants a and b decreases with increasing Sr concentration and becomes almost zero at x = 2.0. Characteristic temperatures, which correspond to antiferromagnetic ordering and structural transition, decrease with increasing Sr concentration. The value of the magnetic susceptibility below 30K increases with increasing Sr concentration. The temperature dependence of the electrical resistivity revealed that Sr substitution significantly suppresses the highly anisotropic electric structure of Ca3Ru2O7. (C) 2007 Elsevier B.V.
