In this work, we investigate the magnetic interaction and associated electronic structure by employing element-resolved x-ray magnetic circular dichroism (XMCD) and angle-resolved photoemission spectroscopy (ARPES), combined with density functional theory (DFT) calculations in GdMn6Sn6. Both ARPES and ...
MnK-edgemagnetic phase transitionMn3MC perovskiteMn 3 M C ( M = Zn and Ga) perovskite has attracted interest because of a variety of magnetic phase transitions. In this work, we measure temperature and magnetic field dependence of X-ray magnetic circular dichroism (XMCD) at Mn K -edge and...
综上所述,我们证明了一种自旋极化策略可以在非磁性催化剂(Mn掺杂RuO2)中产生铁磁耦合,从而使酸性10 mA cm-2 OER活性从无磁场时的200 mV增强到磁场下的低过电位143 mV。元素选择性XMCD实验证明了Ru和Mn离子之间遵循Goodenough-Kanamori规则的铁磁耦合。Mn2+(3+)与RuO2晶格之间的相互作用形成了一种通过磁化观察...
元素选择性 XMCD 实验表明,Ru 离子和 Mn离子之间的铁磁耦合遵循 Goodenough-Kanamori 规则。Mn2+(3+) 与 RuO2 晶格之间的相互作用形成了通过磁化观察到的长程铁磁行为。因此,当施加外磁场时,更多的 Ru 原子磁矩相互平行,为 OER 构建了一个新的自旋极化环境,这在很大程度上提高了其内在活性和稳定性,与量子...
We have investigated the Mn 3d electronic structure of Mn5Ge3 by means of the Mn 2p-3d soft X-ray absorption spectroscopy (XAS) and magnetic circular dichroism (XMCD) experiments. The spectra are similar to those of the itinerant ferromagnetic compound MnSb. The integrated intensity of the XM...

The XAS and XMCD measurement geometries were set to normal incidence, so that both the photon helicity and the magnetic field were normal to the surface. Electronic structure calculations. First-principles density-functional calculations of the spin-polarised band structures were performed using the...

The magnetic interaction between transition metals in Cr-doped manganites: LaCrxMn1−xO3 has been investigated both by soft X-ray magnetic circular dichroism (soft-XMCD) and Monte Carlo simulation. Samples were prepared by conventional solid-state reaction. In the soft-XMCD measurements, we obse...
