  • 15 September 1990
We propose an approximate method for studying steady-state properties and linear stability of the dendritic arrays that are formed in directional solidification of alloys. Our analysis is valid atExpand

Cu spin dynamics and superconducting precursor effects in planes above Tc in YBa2Cu3O6.7.
Spin dynamics at planar sites in oxygen-deficient YBa/sub 2/Cu/sub 3/O/sub 6+//sub x/ have been investigated by nuclear spin-lattice relaxation measurements using /sup 63,65/Cu nuclear quadrupoleExpand

Spatial Period-Doubling Instability of Dendritic Arrays in Directional Solidification.
A directional solidification study of succinonitrile doped with coumarin 152 was performed in which the pulling speed {ital V}{sub {ital P}} was gradually reduced in small steps. A spatialExpand
