Magnetic V embedded in copper evidenced by x-ray magnetic circular dichroism

چکیده
We report the observation of a magnetic moment on vanadium embedded in copper. Using x-ray-absorption spectroscopy and x-ray magnetic circular dichroism we show that the vanadium atomic magnetic moment is strongly dependent on the formation temperature of the VCu alloy. The absorption spectra allow us to distinguish the electronic transitions which are the signature of the magnetic state from the nonmagnetic states. We discuss the temperature dependence of the magnetic moment of vanadium and show that alloys prepared at 250 and 270 K do follow a ferrimagnetic behavior rather than a Curie-Weiss law.

X-ray magnetic dichroism in the III-V diluted magnetic semiconductors
Diluted magnetic semiconductors (DMSs) are semiconductors alloyed with magnetic elements [1]. The physical properties of these materials can be tuned by both charge and spin, thus, they have great potential of being used in a wide variety of spintronic applications, such as magneto-optical, magneto-electrical, and magneto-transport devices. Spintronics (spin+electronics) is the technology that ...
متن کاملTwo-Orbital Kondo Screening in a Self-Assembled Metal-Organic Complex.
Iron atoms adsorbed on a Cu(111) surface and buried under polyphenyl dicarbonitrile molecules exhibit strongly spatial anisotropic Kondo features with directionally dependent Kondo temperatures and line shapes, as evidenced by scanning tunneling spectroscopy. First-principles calculations find nearly full polarization for the half-filled Fe 3dxz and 3dyz orbitals, which therefore can give rise ...

Through an extensive set of SQUID magnetic measurements, X-ray absorption spectroscopy, and X-ray magnetic circular dichroism, we have determined the nature of the metastable photomagnetic phase in the cyano-bridged 3D network Cs(2)Cu(7)[Mo(CN)(8)](4). The photomagnetic effect is induced by the photoconversion of Mo(IV) ions in low spin (LS) configuration (S = 0) into Mo(IV) ions in high spin (...
متن کاملInduced perpendicular magnetization in a Cu layer inserted between Co and Pt layers revealed by x-ray magnetic circular dichroism
We used x-ray absorption spectroscopy and x-ray magnetic circular dichroism to investigate the effects of inserting Cu into Co/Pt interfaces, and found that a 0.4-nm-thick inserted Cu layer showed perpendicularly magnetized properties induced by the proximity effect through the Co and Pt layers. The dependence of the magnetic properties on the thickness of the Cu layers showed that the proximit...
متن کاملBeyond the Heisenberg model: anisotropic exchange interaction between a Cu-tetraazaporphyrin monolayer and Fe3O4(100).
The exchange coupling of a single spin localized at the central ion of Cu-tetraazaporphyrin on a magnetite(100) surface has been studied using x-ray magnetic circular dichroism (XMCD). Sum rule analysis of the XMCD spectra results in Cu spin and orbital magnetic moments as a function of the applied external field at low temperatures (20 K). The exchange coupling is positive for magnetization di...
