Query: Phase diagram of Ca$_{1-x}$Ce$_x$MnO$_3$ thin films studied by X-ray
  magnetic circular dichroism   In the perovskite-type Ca$_{1-x}$Ce$_{x}$MnO$_{3}$ (CCMO), one can control
the transport and magnetic properties through varying Ce content. In the case
of thin films, the properties can also be controlled by epitaxial strain from
the substrate through changing it such as YAlO$_{3}$ (YAO), NdAlO$_{3}$ (NAO),
and LaSrAlO$_{4}$ (LSAO). However, one cannot measure the magnetization of thin
films on NAO substrates by conventional magnetization measurements because of
the strong paramagnetic signals from the Nd$^{3+}$ ions. In order to eliminate
the influence of Nd$^{3+}$ and to identify magnetic phases of the CCMO thin
films, we have performed element-selective X-ray magnetic circular dichroism
(XMCD) measurements of the Mn 2{\it p} core level. By studying the anisotropy
of the XMCD intensity, we could unambiguously determine the magnetic phase
diagram of the CCMO thin films.
