A universal relationship between magnetization and local structure changes below the ferromagnetic transition in La_{1-x}Ca_xMnO_3; evidence for magnetic dimers
L. Downward, F. Bridges, S. Bushart +3
We present extensive X-ray Absorption Fine Structure (XAFS) measurements on La_{1-x}Ca_xMnO_3 as a function of B-field (to 11T) and Ca concentration, x (21-45%). These results reve…

Observation of ferromagnetism above 900 K in Cr-GaN and Cr-AlN
H. X. Liu, Stephen Y. Wu, R. K. Singh +6
We report the observation of ferromagnetism at over 900K in Cr-GaN and Cr-AlN thin films. The saturation magnetization moments in our best films of Cr-GaN and Cr-AlN at low tempera…
