Evidence for the Alternating Next-Nearest Neighbor model in the dynamic behavior of a frustrated antiferromagnet
Adra Carr, John Bowlan, 3 +12
X-ray photon correlation spectroscopy (XPCS) enables us to study dynamics of antiferromagnets. Using coherent soft X-ray diffraction, we resonantly probe Mn and Co Bragg peaks in t…
Probing and controlling terahertz-driven structural dynamics with surface sensitivity
P. Bowlan, J. Bowlan, S. A. Trugman +8
Intense, single-cycle terahertz (THz) pulses offer a promising approach for understanding and controlling the properties of a material on an ultrafast time scale. In particular, re…
Ultrafast spin density wave transition in Chromium governed by thermalized electron gas
C. W. Nicholson, C. Monney, R. Carley +4
The energy and momentum selectivity of time- and angle-resolved photoemission spectroscopy is exploited to address the ultrafast dynamics of the antiferromagnetic spin density wave…
Probing ultrafast spin dynamics in the antiferromagnetic multiferroic HoMnO through a magnon resonance
P. Bowlan, S. A. Trugman, J. Bowlan +5
We demonstrate a new approach for directly measuring the ultrafast energy transfer between elec- trons and magnons, enabling us to track spin dynamics in an antiferromagnet (AFM).…
Bistability of Free Cobalt and Iron Clusters
Xiaoshan Xu, Shuangye Yin, Ramiro Moro +3
The cobalt and iron clusters CoN, FeN (20 < N < 150) measured in a cryogenic molecular beam are found to be bistable with magnetic moments per atom both μN/N 2μB in the ground stat…
Non-classical dipoles in cold niobium clusters
Xiaoshan Xu, Shuangye Yin, Ramiro Moro +3
Electric deflections of niobium clusters in molecular beams show that they have permanent electric dipole moments at cryogenic temperatures but not higher temperatures, indicating…
