Spin Waves and Switching: The Dynamics of Exchange - Biased Co Core - CoO Shell Nanoparticles (2009)
Feygenson, Mikhail, Teng, Xiaowei, Inderhees, Sue E., Yiu, Yuen, Du, Wenxin, Han, Weiqiang, ...
The utility of nanoscaled ferromagnetic particles requires both stabilized moments and maximized switching speeds. During reversal, the spatial modulation of the nanoparticle magnetization evolves in...
Spin Gap and Resonance at the Nesting Wavevector in Superconducting FeSe0.4Te0.6 (2009)
Qiu, Yiming, Bao, Wei, Zhao, Yang, Broholm, Collin, Stanev, V., Tesanovic, Z., ...
Neutron scattering is used to probe magnetic excitations in FeSe_{0.4}Te_{0.6} (T_c=14 K). Low energy spin fluctuations are found with a characteristic wave vector $(0.5,0.5,L)$ that corresponds to...
The ground state of a quantum critical system (2006)
Montfrooij, Wouter, Lamsal, Jagat, Aronson, Meigan, Bennett, Marcus, De Visser, Anne, Kai, Huang Ying, ...
The competition between the tendency of magnetic moments to order at low temperatures, and the tendency of conduction electrons to shield these moments, can result in a phase transition that takes...
