Structural and magnetic properties of Fe65Co 35@Ni05Zn05Fe2O4 composite thin films prepared by a novel nanocomposite technology
Fe65Co35 alloy nanoclusters prepared by using a plasma-gas-condensation method were encapsulated into Ni0.5Zn 0.5Fe2O4 thin film to form new-type films in a nanocluster beam composite film deposition system. An average size of the Fe65Co35 alloy nanoclusters was about 5.5 nm with a narrow size distribution. Compared with that of Ni0.5Zn 0.5Fe2O4 thin film, saturation magnetization of the [email protected] 2O4 composite thin films which contained 6 wt.% Fe 65Co35 alloy nanoclusters was increased by about 64%, while the coercivity was reduced by almost 44.7%. Meanwhile, resistivity still maintained at a high value (1.67 × 1010 μΩ cm). The influence of annealing temperature on structure and magnetic properties of the [email protected] 2O4 composite thin films was also investigated. As the annealing temperature was increased, saturation magnetization rose gradually while coercivity revealed a complicated change tendency. ? 2014 Elsevier B.V. All rights reserved

STCF Conceptual Design Report: Volume 1 -- Physics & Detector
International audienceThe Super -Charm facility (STCF) is an electron-positron collider proposed by the Chinese particle physics community. It is designed to operate in a center-of-mass energy range from 2 to 7 GeV with a peak luminosity of or higher. The STCF will produce a data sample about a factor of 100 larger than that by the present -Charm factory -- the BEPCII, providing a unique platform for exploring the asymmetry of matter-antimatter (charge-parity violation), in-depth studies of the internal structure of hadrons and the nature of non-perturbative strong interactions, as well as searching for exotic hadrons and physics beyond the Standard Model. The STCF project in China is under development with an extensive R&D program. This document presents the physics opportunities at the STCF, describes conceptual designs of the STCF detector system, and discusses future plans for detector R&D and physics case studies
