ABSTRACT
A series of metallic (Co, Ga)-codoped ZnO single crystalline films have been grown by molecular beam epitaxy. All of the films exhibit metallic conducting behavior and high free carrier concentrations. Besides room temperature ferromagnetism, the anomalous Hall effect due to spin-orbit interaction was also found. Both the saturation magnetization and anomalous Hall effect can be tuned by the carrier concentration or conductivity, revealing that the ferromagnetism is carrier mediated in (Co, Ga)-codoped ZnO films. Our experimental observations are consistent with the recent theoretical description of carrier mediated magnetism in Co doped ZnO.

    We report on the magnetic properties and the phonon behavior of epitaxial Pr2NiMnO6 (PNMO) films. The temperature dependence of their magnetic properties shows a ferromagnetic behavior up to 214 K owing to a dominant Ni2+/Mn4+ ordering. The observation of a secondary low-temperature magnetic...

    The influence of epitaxial strain, tuned with tetragonal distortion c/a from 0.965 to 1.034 by choosing different substrates and varying film thickness, on the magnetic and transport properties of Nd0.45Sr0.55MnO3 thin films has been investigated. It is found that epitaxial strain, depending on...
