论文摘要
我们介绍了EU $ _ {2} $ ir $ $ _ {2} $ o $ $ $ _ {7} $的MUON-SPIN光谱测量的深入分析，这是EU $ _ {1-X} $ _ $ _ $ _ {x} $ _ {x} $ iSageTent and Diamagnetic Enternitation＆Diamagnetic Entersance useptiral and ofternal Pristion y。我们的结果证明，仅对于降低温度的磁力量欧盟$ _ {2} $ ir $ $ _ {2} $ o $ $ $ _ {7} $，磁性体积分数的速度异常缓慢增加，这指向其中磁性阶段开发的高度非常常见的属性。我们认为，欧盟$ _ {2} $ ir $ _ {2} $ o $ $ _ {7} $基于$ t_ {n} $的磁液滴的成核而开发的磁性，其连续的增长受到连续产生的磁性HedgeHog Monopoles的需求的限制。
We present an in-depth analysis of muon-spin spectroscopy measurements of Eu$_{2}$Ir$_{2}$O$_{7}$ under the effect of the Eu$_{1-x}$Bi$_{x}$ isovalent and diamagnetic substitution as well as of external pressure. Our results evidence an anomalously slow increase of the magnetic volume fraction upon decreasing temperature only for stoichiometric Eu$_{2}$Ir$_{2}$O$_{7}$, pointing towards highly unconventional properties of the magnetic phase developing therein. We argue that magnetism in Eu$_{2}$Ir$_{2}$O$_{7}$ develops based on the nucleation of magnetic droplets at $T_{N}$, whose successive growth is limited by the need of a continuous generation of magnetic hedgehog monopoles.
