Times Cited Count:43 Percentile:81.58(Materials Science, Multidisciplinary)A frustrated spinel CdCrO undergoes a three-dimensional spin-Peierls transition at = 7.8 K from a cubic paramagnetic to a tetragonal Nel state. The Nel state has a spiral magnetic structure with a characteristic wave vector of when the axis elongated. Here we report our spherical neutron polarimetry experiments to investigate the spiral spin structure in detail. Our results indicate that the spins lie in the plane perpendicular to the direction of the spiral modulation. We also found that the spiral structure in the plane is elliptical with the -component larger by 24% than the -component, suggesting a strong coupling between the magnetic structure and structural distortion. Unpolarized neutron diffraction under an external magnetic field has also been performed. The magnetic field dependence suggests existence of magnetic anisotropy in the Nel state, which is consistent with our previous inelastic studies.

We have developed an Electron Tracking Compton Camera (ETCC), which provides a well-defined Point Spread Function (PSF) by reconstructing a direction of each gamma as a point and realizes simultaneous measurement of brightness and spectrum of MeV gamma-rays. Here, we present the results of the gamma-imaging-spectroscopy with ETCC tested at the research reactor at the Institute for Integrated Radiation and Nuclear Science, Kyoto University.

Polarized neutron scattering exaperiments have been performed on LaBaCuO and LaSrCuO with intent to elucidate a possible effects of stripe structure to the spin dynamics. Low energy ( meV) data demonstratre that in the former sample, which has a well-ordered stripe state with Cu spins lying in the CuO plane at 10 K, spins fluctuate only in the plane. On the other hand, the latter sample, which has very weak stripe order, shows isotropic spin fluctuation. This implies that low energy magnetic excitations are stringly affected by the stripe order.

Polarized neutron scattering is an important tool to clarify the existence of chirality. Furthermore, it also gives useful information on magnetic anisotropy of the spin fluctuations in the diagonal incommensurate phase. We performed polarized neutron scattering experiments in lightly-doped LaSrCuO. The results showed that the chiral terms are almost negligible, indicating that there is no chirality or that the two chirality domains are equally populated. The diagonal terms originate from the magnetic anisotropy in the antiferromagnetically ordered phase. It was found that the spins lie almost in the CuO plane although a finite out-of-plane component was observed. It was also found that there exists a small anisotropy in the CuO plane and the spin component is larger along the b axis, suggesting the remnant of anisotropy in pure LaCuO.
