Currently one of the biggest challenges in spintronics is the generation and control of a spin polarized current at room temperature. Spin injection from europium monoxide is of considerable interest in technology and material science because of its high spin splitting (~0.6eV) and large magnetic moment (~7uB). However, its low Tc (~70 K) makes it difficult to be implemented in any room temperature devices. La increases the Tc of EuO to up to 200K (highest Tc for doped EuO). This vast increase renders this system a very promising environment to study spin-injection by using a ferromagnetic semiconducting oxide. In this work we propose to study the magnetic moment of La-doped as well as oxygen deficient EuO. By using PNR at RAL it will bepossible to determine with great accuracy the magnetic moment and gain a better understanding on the exchange interactions in rare earth oxides.
