- Title:
- Spin Waves and Magnetic Ordering in the Quasi-One-Dimensional $S=\frac{1}{2}$ Antiferromagnet ${\mathrm{BaCu}}_{2}{\mathrm{Si}}_{2}{\mathrm{O}}_{7}$
- Abstract:
- Elastic and inelastic neutron scattering were used to study the ordered phase of the quasi-one-dimensional spin-1/2 antiferromagnet BaCu2Si2O7. The previously proposed model for the low-temperature magnetic structure was confirmed. Spin-wave dispersion along several reciprocal-space directions was measured and interchain, as well as in-chain exchange constants were determined. A small gap in the spin-wave spectrum was observed and attributed to magnetic anisotropy effects. The results are discus... »
