Journal ArticleDOI
High-resolution x-ray and light-scattering study of critical behavior associated with the nematic—smectic- A transition in 4-cyano-4′-octylbiphenyl
D. Davidov,Cyrus R. Safinya,M. Kaplan,S. S. Dana,R. Schaetzing,Robert J. Birgeneau,J. D. Litster +6 more
TL;DR: In this paper, a high-resolution x-ray study of the mass-density fluctuations and a light-scattering study of bend-mode-director fluctuations associated with the nematic-smectic-$A$ phase transition in 4-cyano-4-ensuremath{'}-octylbiphenyl (8CB) was carried out.
Journal ArticleDOI
Successive antiferromagnetic phase transitions in single-crystal La2CoO4.
Kazuyoshi Yamada,Masaaki Matsuda,Yasuo Endoh,B. Keimer,Robert J. Birgeneau,S. Onodera,Junichiro Mizusaki,T. Matsuura,Gen Shirane +8 more
TL;DR: In contrast to the S = 1/2 Heisenberg system La/sub 2/CuO/sub 4/, well-defined two- dimensional Ising critical phenomena are observed and the two-dimensional spin correlations at T>T/sub N/ are almost entirely elastic.
Journal ArticleDOI
Neutron scattering study of the lattice dynamical phase transitions in KMnF3
TL;DR: In this article, the authors studied the structural phase transition in KMnF3 at 186.6°K and 91.5°K, and found that the soft phonon mode intensities diverge in a manner that is typical of a second order phase transition.
Journal ArticleDOI
Critical behavior of a site-diluted three-dimensional Ising magnet
Robert J. Birgeneau,R. A. Cowley,Gen Shirane,Hideki Yoshizawa,D. P. Belanger,A. R. King,V. Jaccarino +6 more
TL;DR: In this article, the site-diluted three-dimensional Ising antiferromagnet Fe/sub 1-x/Zn/sub x/F/sub 2/ has been studied with the use of neutron scattering and linear birefringence techniques.
Journal ArticleDOI
High-resolution x-ray-scattering study of the commensurate-incommensurate transition of monolayer Kr on graphite
Peter W. Stephens,Paul A. Heiney,Robert J. Birgeneau,Paul M. Horn,David E. Moncton,George Brown +5 more
TL;DR: In this article, a detailed high-resolution, x-ray-scattering study of the commensurate-incommensurate transition of Kr on exfoliated graphite powder is presented.
