Onset of antiferromagnetism in heavy fermion metals
A. Schroder, G. Aeppli, R. Coldea +6
There are two views of antiferromagnets. The first proceeds from atomic physics, which predicts that atoms with unpaired electrons develop magnetic moments. In a solid, the couplin…
Spin gap and magnetic coherence in a clean high-T_c superconductor
B. Lake, G. Aeppli, T. E. Mason +7
A notable aspect of high-temperature superconductivity in the copper oxides is the unconventional nature of the underlying paired-electron state. A direct manifestation of the unco…
Scaling of magnetic fluctuations near a quantum phase transition
A. Schroder, G. Aeppli, E. Bucher +2
We use inelastic neutron scattering to measure the magnetic fluctuations in a single crystal of the heavy fermion alloy CeCu_5.9Au_0.1 close to the antiferromagnetic quantum critic…
New magnetic coherence effect in superconducting La_{2-x}Sr_{x}CuO_{4}
T. E. Mason, A. Schroder, G. Aeppli +2
We have used inelastic neutron scattering to examine the magnetic fluctuations at intermediate frequencies in the simplest high temperature superconductor, La_{2-x}Sr_{x}Cu_{4}. Th…
