Abstract
We have determined the structure and magnetic properties of flux-grown single crystals of the triple-layer ruthenate by x-ray diffraction and magnetic susceptibility measurements, respectively. The orthorhombic unit cell has Pbam space group symmetry and contains two crystallographically independent triple layers. The octahedra in the outer two layers of each triple layer are rotated by an average of 5.6° around the c axis, while the octahedra of the inner layers are rotated in the opposite sense by an average of 11.0°. The Curie temperature of these ferromagnetic crystals is with a saturated moment of ion. Thus is a layered ferromagnetic ruthenate in the Ruddlesden-Popper (R-P) series which also includes the unconventional superconductor the enhanced paramagnetic metal and the pseudocubic ferromagnetic metal
