Dilute magnetism and vibrational entropy in Fe2Al5
Ji Chi, Xiang Zheng, Sergio Y. Rodriguez +5
Fe2Al5 contains a Fe-Al matrix through which are threaded disordered one-dimensional chains of overlapping Al sites. We report magnetic, nuclear-magnetic-resonance (NMR), and speci…
NMR experiments and electronic structure calculations in type-I BaAlGe clathrates
Weiping Gou, Sergio Y. Rodriguez, Yang Li +1
We describe 27Al NMR experiments on Ba8AlxGe46-x type-I clathrates coupled with ab initio computational studies. For x=16, calculated spectra determined by the ab initio results ga…
Ferromagnetism and Metamagnetism in Copper-doped Germanium Clathrate
Yang Li, Weiping Gou, Ji Chi +1
Cu-doped type-I germanium clathrate can exhibit dilute magnetism, including ferromagnetism, antiferromagnetism, and metamagnetic transitions up to 90 K. 63Cu NMR measurements confi…
Structure and stability of Ba-Cu-Ge type-I clathrates
Yang Li, Ji Chi, Weiping Gou +2
We have prepared samples of nominal type Ba(8)Cu(x)Ge(46-x) by induction melting and solid state reaction. Analysis shows that these materials form type-I clathrates, with copper c…
