Onset of antiferromagnetism in heavy-fermion metals
Article Abstract:
Research is presented concerning the development of a method which allows for discrimination between the two major theoretical descriptions of antiferromagnets at a 'quantum critical point'.

Direct measurement of antiferromagnetic domain fluctuations
Article Abstract:
The direct measurement of the fluctuations in the nanometre-scale superstructure of spin- and charge density waves associated with antiferromagnetism in elemental chromium is presented. The study has highlighted a useful measurement tool for antiferromagnetic domain wall engineering and has also revealed the spin dynamics in the simplest antiferromagnet.

Spin gap and magnetic coherence in a clean high-temperature superconductor
Article Abstract:
Inelastic neutron scattering was used to determine the wavevector-dependence of spin pairing in La(sub2-x)SrxCuO(sub4), a high-temperature superconductor. The spin paring energy was found to be wavevector independent, although superconductivity significantly changed the wavevector dependence of spin fluctuations at higher energies. The data provides proof that spin excitations in the superconducting state do not parallel charge excitations in the way assumed.
