Electronic structure change with Gd doping of HfO2 on silicon, The
Contributor:Losovyj, Ya. B.; Ketsman, Ihor; Sokolov, A.; Belashchenko, K. D.; Dowben, P. A.; Tang, Jinke; Wang, Zhenjun
Gd-doped HfO2 films deposited on silicon substrates undergo a crystallographic change from monoclinic to fluorite cubic phase with increasing Gd concentrations. The crystallographic phase change is accompanied by a small ...
Granular growth of Fe3O4 thin films and its antiphase boundaries prepared by pulsed laser deposition
Contributor:Zhou, W. L.; Wang, K.-Y.; O'Connor, C. J.; Tang, Jinke
Fe3O4 thin film prepared by pulsed laser deposition on Si (100) substrate has been investigated by transmission electron microscopy from plane and cross-sectional views. The thin film, which shows a spinel structure as ...
Current-controlled channel switching and magnetoresistance in an Fe3C island film supported on a Si substrate
Contributor:Tang, Jinke; Dai, Jianbiao; Wang, Kaiying; Zhou, Weilie; Ruzycki, Nancy; Diebold, Ulrike
A film of magnetic Fe3C islands separated by nanochannels of graphite was prepared with pulsed laser deposition on a Si substrate with a native SiO2 surface. When the temperature is increased above 250 K the resistance ...
Synthesis and superconductivity of intermetallic compounds Y2NixB8−xC2, YNixCu2−xB2C, and YNixCu2−xSi2C
Contributor:Zhao, Wei; Tang, Jinke; Lee, Young-sook; O’Connor, Charles J.
Borocarbide and silicocarbide intermetallic Y2NixB82xC2 (x = 1, 2, 3, 5), YNiCuB2C, and YNixCu22xSi2C (x = 0, 2) were prepared and their superconductivity was studied. The results indicated that with the change of the ratio ...
Magnetic and magnetotransport properties of intermetallic SmMn2Si2
Contributor:Zhao, M.; Sun, C.; Wang, L.; Su, Q.; Zhao, W.; Tang, Jinke
The magnetic properties of naturally layered intermetallic compound SmMn2Si2 with textured structure have been studied. There exist a ferromagnetic transition at 35 K and two antiferromagnetic transitions at 120 and 230 ...
Enhanced low field magnetoresistance in Sr2FeMoO6-glass composites
Contributor:Wang, Xianjie; Zhang, Xingquan; Sui, Yu; Cheng, Jinguang; Liu, Zhiguo; Miao, Jipeng; Huang, Xiqiang; Lu, Zhe; Qian, Zhengnan; Su, Wenhui; Tang, Jinke
In this paper, we report the enhancement of the low field magnetoresistance in Sr2FeMoO6-glass composites with different wt% percents of glass. The crystal structure of Sr2FeMoO6 does not change by adding glass, and the ...
Magnetoelectric coupling at the EuO/BaTiO3 interface
Contributor:Cao, S.; Liu, P.; Tang, Jinke; Lu, H.; Bark, C.-W.; Ryu, S.; Eom, C. B.; Gruverman, A.; Dowben, P. A.
Magnetization modulation by ferroelectric polarization switching is reported for the ferromagneticferroelectric EuO/BaTiO3 heterostructure. The value of the magnetization critical exponent β is consistent with the expected ...
Direct observation of strain fields in epitaxial growth Fe3O4 thin films on MgO substrates
Contributor:Chen, Y. X.; Chen, C.; Zhou, W. L.; Wang, Z. J.; Tang, Jinke; Wang, D. X.; Daughton, J. M.
Fe3O4 thin films with a thickness of about 140 nm have been deposited on MgO (001) substrates by reactive sputtering. Microstructural studies indicated that monocrystalline Fe3O4 thin films were epitaxially grown on the ...
