• Short: III/29a Title: Low Frequency Properties of Dielectric Crystals: Second and Higher Order Elastic Constants Author: Every, A.G.; McCurdy, A.K. Editor: Nelson, D.F. Source: Landolt-Börnstein, New Series Volume: III/29a Year: 1992 ISBN: 3-540-54410-0 ISBN: 978-3-540-54410-4 Internet Resource: DOI:10.1007/b44185 RefComment: 890 figs., XIV, 743 pages. Hardcover Abstract: Some years after the publication of Vol. III/11 and its supplement III/18 dealing with elastic, piezoelectric, pyroelectric and optical properties of crystals, a complete recompilation of the data of these volumes and of new data was performed. Because of the growth of this subject matter it was found convenient to divide the material into four volumes, III/29a and b for the low frequency properties and III/30a and b for high frequency propertiesof dielectric crystals. The first subvolume III/29a contains exclusively second and higher order elastic constants including temperature and pressure coefficients.

The structure data of the remaining inorganic compounds and the elements are dealt with in volumes III/6 and III/14, while the organic compounds are treated in volumes III/5 and III/10. The systematic arrange-ment is based on the anions ordered according to "key elements", since this system allows the arrangement of the crystal structure data in such a way that both chemical and crystallographical relationships c
