Damascelli, L. Tjeng, C. Hooley, Andriy Nevidomskyy, E. Morosan
The interplay of Kondo screening and magnetic ordering in strongly correlated materials containing local moments is a subtle problem. Usually the number of conduction electrons per unit cell matches or exceeds the number of moments, and a Kondo-screened

Powder X-ray structural analysis and band gap measurements for (CaxSr2-x)MnWO6 (x = 0.25, 0.5, 0.75, 1.5, 1.75).

The structure, powder diffraction patterns and band gap measurements of a series of manganese- and tungsten-containing alkaline-earth double perovskites (CaxSr2-x)MnWO6 (x=0.25, 0.5, 0.75, 1.5, 1.75) have been investigated. Powder X-ray diffraction

Metal-Insulator transition in Doped Barium Plumbate

Andreza M. Eufrasio, Ian L. Pegg, Nikolaus Deems, Biprodas Dutta, Winnie Wong-Ng, Qingzhen Huang
Solid solutions in the Ba(Pb1−xSrx)O3−z system were prepared by aliovalent substitution of Pb4+ by Sr2+ ions to investigate the effect of cation stoichiometry on thermal and electrical properties as x was varied between 0 and 0.4, in the temperature range

A Distinct Spin Structure and Giant Baromagnetic Effect in MnNiGe Compounds with Fe-Doping

Feiran Shen, Houbo Zhou, Fengxia Hu, Jian-Tao Wang, Hui Wu, Qingzhen Huang, Jiazheng Hao, Zibing Yu, Yihong Gao, Yuan Lin, Yangxin Wang, Cheng Zhang, Zhuo Yin, Jing Wang, Sihao Deng, Jie Chen, Lunhua He, Tianjiao Liang, Jirong Sun, Tongyun Zhao, Baogen Shen
Spin structure of a magnetic system results from the competition of various exchange couplings. Pressure driven spin structure evolution, through altering interatomic distance and hence electronic structure, produces baromagnetic effect(BME), which has
