被引用回数:2 パーセンタイル:21.2(Physics, Multidisciplinary)We have performed X-ray magnetic circular dichroism (XMCD) measurements on the iron-based superconductor SrVFeAsO to study the origin of weak ferromagnetism (WFM) reported for this compound. While Fe 3d electrons show a magnetic response similar to the other iron pnictides, signals from V 3d electrons remain finite at zero magnetic field and may be responsible for the WFM.
