Support and Extension of the Rotational Model of Thin Film Magnetization
This paper describes the magnetic behavior of some thin permalloy films in terms of the rotational model of Stoner and Wohlfarth. Experimental evidence is shown for the existence of a single domain whose orien...

Electron Transport Phenomena and Oscillatory Behavior in the Lattice Conductivity of an Antimony Single Crystal in a Magnetic Field at Low Temperature
With the magnetic field parallel to the trigonal direction, the experimental coefficients of the transport effects have been measured in the basal plane of an antimony crystal, i.e., in a transverse field. The...

Standards and Correction Procedures in Electron-Probe Analysis of Rock-Forming Minerals
A large proportion of the substances which fall under the heading of rock-forming minerals consist of silicates and oxides incorporating elements from Z =11 (Na) to Z = 28 (Ni) in addition to oxygen and hydrogen....

Observations of Supernova Remnants in the Large Magellanic Cloud with the Einstein Observatory
As the nearest extragalactic system, the Large Magellanic Cloud (LMC) is destined to play a major role in understanding the X-ray emission from all normal galaxies including our own. Classed as a prototype Sb(...

A Soft X-Ray Study of the Large Magellanic Cloud
A survey of the Large Magellanic Cloud (LMC) has been carried out with the imaging X-ray telescope aboard the Einstein Observatory. Ninety-seven sources were detected. On statistical grounds, we estimate that les...

An X-Ray Survey of Supernova Remnants in the Large Magellanic Cloud
The last supernova (SN) observed in the Galaxy occurred ~375 years ago and it is clear that progress in SN research would be glacial at best if we were limited to the study of galactic events. Although the fir...

Research on Intensity Distribution of Multi-Order SRS in an Optical Fiber
This paper presents a theoretical analysis as well as an experimental investigation on the relative intensities of multi-order stimulated Raman scattering (SRS) in an optical fiber. Our analysis shows that the...

Length Scales and the Quantised Hall Effect
We have extended earlier measurements on the frequency dependence of the quantised Hall resistance in Silicon inversion layers to higher frequencies and magnetic fields. The frequencies reduce the transport le...

Epa Analysis of Frequency Dependent Loss Data For a-Ge and a-Si
There have recently been several improvements of ac Hop** conductivity theory. Movaghar and co-workers 1,2 Develop a rndom walk model. In the “extended pair approximation” Summerfield and Butcher3,4 analyse the...

Extragalactic Supernova Remnants
Because the supernova remnants (SNRs) in other galaxies are at well-defined distances and because in many cases the reddening within extragalactic samples is more uniform than is the case for the Galactic SNR ...

Crystal Growth of ScBO3:Cr 3+ — A New Near-IR Tunable Laser Crystal
Since the discovery of the alexandrite room-temperature tunable laser [1], much effort has been expended in exploring new laser materials and several new room-temperature tunable laser hosts [2] have been disc...

A Comment on the Seyfert Environment
The study on the Seyfert environment has been of considerable interest lately, since it is believed that the tidal force of a close companian may drive gas into the inner region and either fuel nuclear activit...

Measurement of the Topology of Large-Scale Structures in Turbulent Reacting Flows
Turbulent combustion involves a complex interplay between fluid motion and chemistry. A widely held view is that large-scale structures play an important role in this interaction. Experimental work that concen...
