Crossover from commensurate to incommensurate antiferromagnetism in stoichiometric NaFeAs revealed by single-crystal 23Na,75As-NMR experiments
NaFeAs NMR incommensurate antiferromagnetism 111-type iron arsenide
2010/11/18
We report results of 23Na and 75As nuclear magnetic resonance (NMR) experiments on a
self-flux grown high-quality single crystal of stoichiometric NaFeAs. The NMR spectra revealed
a tetragonal to tw...
Memory State Feedback Control for Singular Systems with Multiple Internal Incommensurate Constant Point Delays
Singular systems Multiple internal point delays Descriptor integral-inequality
2008/12/31
In this paper, the problem of delay-dependent stabilization for singular linear continuous-time systems with multiple internal incommensurate constant point delays (SLCS-MIID) is investigated. The con...

Characterization of the high-temperature modifications of incommensurate tridymite L3-To(MX-1) from 25 to 250∑C
Characterization high-temperature modifications incommensurate tridymite L3-To(MX-1)
2012/4/1
Incommensurate tridymite L3-TO(MX-1) shows a cascade of five phase transitions at 65,110, 150, 200, and 380 8C upon heating. The X-ray diffraction patterns were investigated with a Buerger precession ...
