Nanosecond infrared pulsed laser deposition of cobalt ferrite thin films on Si (100) substrates.

Abstract

2018 E-MRS Spring Meeting. June 19 – 21, 0f 2018, at the Convention Centre of Strasbourg (France). .-https://www.european-mrs.com/meetings/2018-spring/exhibitionCobalt ferrite has attracted interest in various fields such as high-temperature superconductivity, spintronics, microelectronics and magnetic applications. Cobalt ferrite is a mixed iron (III) and cobalt (II) oxide with a spinel-related structure. Our work is focused on understanding the growth of cobalt ferrite thin films on Si (100) by pulsed laser deposition (PLD). The study is aimed at investigating the influence that deposition parameters such as substrate temperature, target-substrate distance or oxygen partial pressure have on the physicochemical properties of the obtained films and, in particular, in cation oxidation states, cation distribution and crystal quality
