Thermal neutron irradiation of synthetic type Ib diamond, followed by annealing, results in a number of paramagnetic point defect centers. One of these is the composite defect designated W29. Previous EPR measurements have shown that the W29 center (

The rare-earth kagome systems R 3Ga5SiO14 (R = Nd or Pr) exhibit cooperative paramagnetism at low temperatures. Evidence for correlated spin clusters in these weakly frustrated systems has previously been obtained from neutron scattering and from ESR

Measurements of the electrical conductivity and the Hall coefficient have been made on polycrystalline yttrium-doped tungsten oxide, YxWO3, for 0.05 ≤ x ≤ 0.20. This range of x includes the predicted metal–insulator transition. The results are

The rare earth kagome systems R3Ga5SiO[Formula: see text] (R = Nd or Pr), which are weakly frustrated antiferromagnets, do not exhibit long-range order at temperatures down to 40 mK as revealed by neutron scattering. The neutron experiments provide e

The P1 nitrogen defect centres in natural type Ia diamonds have been exploited in dynamic nuclear polarization (DNP) of the 13C nuclei (1.1% abundant) via the solid-effect. We have achieved sufficiently large 13C polarizations in some diamonds to obs
