Strontium stannate (Sr3Sn2O7) PLD Target

Introduction to Strontium Stannate

Strontium stannate is a Ruddleson Popper perovskite material with the chemical formula Sr3Sn2O7. It has gained significant attention in the field of materials science and engineering due to its unique properties and potential applications in electronic devices. Sr3Sn2O7 along with several other Ruddleson-Popper Perovskite exhibit hybrid improper ferroelectricity (HIF) which is a way to realize multiferroic effect avoiding the incompatibility of electronic configuration in so called proper ferroelectrics. Hybrid improper ferroelectricity is defined as the ferroelectricity caused by the coupling of two non-polar octahedral rotation modes of different symmetry 

Structural and Chemical Properties of Strontium Stannate

Ruddlesden-Popper (R-P) perovskite oxides have the formula (A'O) (ABO3)2, where A, A’ and B are cations, and the ‘2’ represents the number of oxygen octahedral layers connected along the c axis. The B ion is in the center of the oxygen octahedron, the A and A’ ion are in the interspace of the octahedron with coordination numbers of 12 and 9, respectively.
