Abstract

We use time-resolved X-ray photoelectron spectroscopy to probe the electronic and magnetization dynamics in FeRh films after ultrafast laser excitations. We present experimental and theoretical results which investigate the electronic structure of FeRh during the first-order phase transition, identifying a clear signature of the magnetic phase. We find that a spin polarized feature at the Fermi edge is a fingerprint of the magnetic status of the system that is independent of the long-range ferromagnetic alignment of the magnetic domains. We use this feature to follow the phase transition induced by a laser pulse in a pump-probe experiment and find that the magnetic transition occurs in less than 50 ps and reaches its maximum in 100 ps.

摘要

我们使用时间分辨X射线光电子能谱来探测超快激光激发后FeRh薄膜中的电子和磁化动力学。我们展示了实验和理论结果，这些结果研究了FeRh在一级相变过程中的电子结构，确定了磁相的清晰特征。我们发现费米边缘处的自旋极化特征是系统磁状态的指纹，它与磁畴的长程铁磁排列无关。我们利用这一特征在泵浦-探测实验中跟踪激光脉冲诱导的相变，发现磁转变在不到50皮秒内发生，并在100皮秒内达到最大值。
