Tunable electronic and magnetic properties in Eu<sub>1-x</sub>La<sub>x</sub>TiO<sub>3</sub> (0&lt; x &lt;1)

ORAL

Abstract

We explore the magnetic transitions and electronic structures of strained Eu1-xLaxTiO3 (0<x<1) grown by oxide molecular beam epitaxy (MBE). In bulk, undoped EuTiO3 (Ti4+) is insulating and antiferromagnetic with a Néel temperature of ~ 5.5 K, while LaTiO3 (Ti3+) is a Mott insulator with a Néel temperature of ~ 160K. Previous experiments of doping EuTiO3 or LaTiO3 thin films show novel emergent states, such as ferromagnetism, skyrmions, and metal-insulator transition. We show the studies of high-quality thin films of Eu1-xLaxTiO3 from x = 0 to x = 1. With a different ratio of Eu2+/La3+, we observe a series of transitions in the films. We will complete the phase diagram of this system.
