用muSR检测SmFeAsO1-xFx中的本征铁磁杂质相
Intrinsic ferromagnetic impurity phases in SmFeAsO1-xFx detected by muSR
摘要:
我们报告的muSR测量SmFeAsO 1-xFx,这有助于我们确定的签名稀释的铁磁性夹杂物,无处不在的铁pnictides。这些杂质的特征在于接近室温的居里温度,并且它们似乎对注入的μ子的不可忽略的磁弛豫负责,这不应与固有的磷属元素化物性质混淆。
英文摘要:
We report about muSR measurements on SmFeAsO1-xFx which helped us to identify the signature of diluted ferromagnetic inclusions, ubiquitous in the iron pnictides. These impurities are characterized by a Curie temperature close to room temperature and they seem responsible for a non negligible magnetic relaxation of the implanted muons, that should not be confused with intrinsic pnictide properties.
