The Ruddlesden-Popper (RP) series of strontium ruthenates Srn+1RunO3n+1 manifests an interesting variety of phenomena. Here we focus on the crystal growth and on the detailed characterization of the ferromagnetic SrRuO3 (n=∞, 1-1-3) and Sr4Ru3O10 (n=3, 4-3-10) systems. A peculiar property of the mixed 1-1-3 materials CaxSr1−xRuO3 with x=0, 0.3, 0.5, 0.7 concerns the tuning of electronic and magnetic features by substitution of smaller Ca2+ ions into the Sr2+ sites while not changing the electronic configuration [1].The triple-layer ruthenate compound Sr4Ru3O10 exhibits a ferromagnetic transition at TC=105 K followed by an additional magnetic transition at TM=50 K which remains matter of controversy. This layered material also shows strong anisotropy concerning the application of magnetic fields [2]. Large single-crystals of Sr4Ru3O10 could be grown by the floating-zone technique and were characterized by structural and magnetization measurements.
