Instability of a Smooth Solid-Liquid Interface During Solidification
It is shown that the cellular substructure observed in binary alloy crystals grown from a melt of known concentration can be eliminated by the proper choice of growth conditions. For a given solute concentrati...

Study of the Resonant Phonon Scattering in KCl:Li Using the Spin-Phonon Interaction
The recent interest in defect modes has been fueled in large measure by their effect on the low temperature thermal conductivity of the host crystal. Beginning with the work of Walker and Pohl,(1) the change in t...

Phonon-Defect Interaction
In this chapter we wish to discuss the interaction of phonons with defects. We will only consider the effect of this interaction on the phonons themselves. The study of the properties of defects in crystals is...

Geomagnetic intensity in Athens between 2000 BC and AD 400
MEASUREMENTS of the intensity in Athens of the geomagnetic field between 2000 BC and AD 400 are reported here. The material from which the intensity was determined consisted primarily of sherds from the Agora exc...

Time–temperature relations in the magnetization of assemblies of single domain grains
A theory for important magnetization processes such as magnetic viscosity and the production of a moment on cooling in a magnetic field is presented here. The results for viscous phenomena differ from those ob...

Early archaeological sites, hominid remains and traces of fire from Chesowanja, Kenya
Recent investigations of Lower Pleistocene sites at Chesowanja have yielded in situ Oldowan and Oldowan-like stone artefacts, evidence of fire and a fragmentary ‘robust’ australopithecine cranium. Burnt clay foun...

Errors and resolution of thermal techniques for obtaining the geomagnetic intensity
Techniques designed to obtain the intensity of the geomagnetic field by thermal demagnetization are subject to error due to differences between the ancient and laboratory cooling rate1–3 and alteration in the phy...

Viscous magnetization
The first test of a theory of viscosity has been possible using experimental results published recently by Dunlop1. This has been accomplished by actually calculating the moment produced as a function of time and...

Re-evaluation of Greek archaeomagnitudes
A new technique is used to determine the secular variation of the geomagnetic ancient field in Athens. The results indicate that published Greek archaeomagnitudes were seriously affected by alteration. It is s...

Discussion in Session 2 “Innovative Methods of Teaching”
Dr. Jones agreed that the availability concept was both more fundamental and an easier concept to grasp than the Gibbs function, so that materials scientist and chemists might perhaps use availability in prefe...

Improving the accuracy of geomagnetic intensity measurements
Many palaeomagnetists believe that, when properly measured, geomagnetic intensities can be obtained with a precision of better than 10% (R. S. Coe, personal communication). But published results do not appear ...
