Origin of the magnetic moments in La0.65Pb0.35MnO3 epitaxial thin films
نویسندگان
چکیده
Crystalline films of La0.65Pb0.35MnO3 grown on ~100! LaAlO 3 substrates by rf sputtering have been investigated using magnetic circular dichroism and inverse photoemission spectroscopy. We find evidence for strong hybridization between unoccupied levels associated with Mn 3d and O 2p states. The oxygen atoms ‘‘pick-up’’ a small magnetic moment through hybridization with Mn. © 2000 American Institute of Physics. @S0021-8979~00!41908-0#

Ultraviolet detectors based on annealed zinc oxide thin films: epitaxial growth and physical characterizations
In this report, ultraviolet (UV) detectors were fabricated based on zinc oxide thin films. The epitaxial growth of zinc oxide thin films was carried out on bare glass substrate with preferred orientation to (002) plane of wurtzite structure through radio frequency sputtering technique. The structural properties indicated a dominant peak at 2θ=34.28º which was matched with JCPDS reference card N...
متن کاملDependence of Magnetic Properties on Laser Ablation Conditions for Epitaxial La_{0.6}Sr_{0.4}MnO_{3} Thin Films Grown by Pulsed Laser Deposition
Epitaxial La0:6Sr0:4MnO3 (LSMO) thin films were grown by pulsed laser deposition. Relationships between magnetic properties of LSMO epitaxial thin films and ablation conditions such as ablated spot area and total incident laser energy in a pulsed laser deposition technique were studied. Ablated spot area was controlled by changing the focus lens position and total laser energy. Epitaxial growth...

Ferrimagnetic Mn2FexGa (0.26 x 1.12) thin films have been characterized by x-ray diffraction, magnetometry, x-ray absorption spectroscopy, x-ray magnetic circular dichroism, and Mössbauer spectroscopy with the aim of determining the structure and site-specific magnetism of this tetragonal, D022-structure Heusler compound. High-quality epitaxial films with low root-mean-square surface roughness ...
متن کاملEffect of Cobalt Concentration on Structural and Magnetic Properties of Co-Fe Thin Films
Co-Fe films were electrodeposited on Cu substrate from electrolytes with different Co concentration levels. X-ray diffraction (XRD) was used to investigate the films crystal structures. The results indicate that if the Co concentration is less that the Fe concentration, the cubic structure appears in the films, while the hexagonal structure dominates when the C...

In this paper, the effect of magnetic field on the morphology, structure and magnetic properties of electrodeposited FeCu/Cu thin films was investigated. The films were deposited on Au2PdAg/glass substrates using electrodeposition technique in potentiostatic control. The magnetic fields of 5000 and 7000 Oe were applied on deposition bath during deposition. Two series of thin films were prepared...
