Magnon-mediated thermal transport in antiferromagnets: the link to momentum-resolved magnon lifetime data
S. P. Bayrakci, B. Keimer, D. A. Tennant
Transport currents in solids decay through collisions of quasiparticles with each other and with defects or boundaries. Since information about collisional lifetimes is difficult t…
Lifetimes of antiferromagnetic magnons in two and three dimensions: experiment, theory, and numerics
S. P. Bayrakci, D. A. Tennant, Ph. Leininger +5
A high-resolution neutron spectroscopic technique is used to measure momentum-resolved magnon lifetimes in the prototypical two- and three-dimensional antiferromagnets Rb2MnF4 and…
Doping induced magnetic clusters and Co spin state transition in Na_xCoO_2 with 0.78<x<.97
C. Bernhard, Ch. Niedermayer, A. Drew +7
By muon spin rotation we investigated the magnetic properties of a series of highly Na doped NaxCoO2 single crystals with 0.78(1)<x<0.97(1). Our data provide evidence for an intrin…
Density and well width dependences of the effective mass of twodimensional holes in (100) GaAs quantum wells measured by cyclotron resonance at microwave frequencies
H. Zhu, K. Lai, D. C. Tsui +5
Cyclotron resonance at microwave frequencies is used to measure the band mass (m_b) of the two-dimensional holes (2DH's) in carbon-doped (100) GaAs/AlxGa1-xAs heterostructures. The…
Spin-Wave Lifetimes Throughout the Brillouin Zone
S. P. Bayrakci, T. Keller, K. Habicht +1
We use a neutron spin-echo method with eV resolution to determine the lifetimes of spin waves in the prototypical antiferromagnet MnF over the entire Brillouin zone. A theor…
Magnetic ordering and spin waves in
S. P. Bayrakci, I. Mirebeau, P. Bourges +6
NaCoO, the parent compound of the recently synthesized superconductor NaCoO:HO, exhibits bulk antiferromagnetic order below K for 0.75 …
