Issue Date: | Sep-1991 | Citation: | Kuok, M.H.,Lee, L.H.,Ishibashi, Y. (1991-09). Raman scattering study of the low-temperature phase transition in K 2Ba(N02)4. Journal of the Physical Society of Japan 60 (9) : 3045-3048. ScholarBank@NUS Repository. | Abstract: | Raman scattering measurements of K2Ba(N02) 4 at low temperatures have been carried out. No soft mode related to the low-temperature transition was observed, implying that the transition is quite likely of the order-disorder type. It is found that the full width at half-maximum of the lowest-lying mode in the (YY) polarization has a linear temperature dependence. | Source Title: | Journal of the Physical Society of Japan | URI: | http://scholarbank.nus.edu.sg/handle/10635/97735 | ISSN: | 00319015 |
