A process for producing novel air-stable coated particles of a magnetic transition metal-rare earth alloy. An organometallic compound which decomposes at a temperature below 500 DEG C is heated to produce a metal vapor which is contacted with particles of a transition metal-rare earth alloy to deposit a metal coating thereon. The coated particles are heated at a temperature ranging from 50 DEG C to 200 DEG C for a period of time sufficient to increase their intrinsic coercive force by at least… 
From the interstellar medium to planetary atmospheres via comets
Laboratory experiments on the trapping of gases by ice forming at low temperatures implicate comets as major carriers of the heavy noble gases to the inner planets. Recent work on deuterium in Comet
Can the Sodium Tail of Comet Hale-Bopp Have a Dust-Impact Origin?
Consideration is given to the possible mechanisms responsible for the production of the atomic sodium tail of comet Hale-Bopp. It is shown that both photosputtering and ion sputtering of nonvolatile
Comet Chemistry: Obtaining Clues to the Formation and Evolution of the Solar System with High-Resolution Infrared Spectroscopy
Comets are icy leftovers from the formation of the solar system about 4.5 billion years ago. Because they have been stored at cold temperatures and their interiors have been protected by an
Spectroscopy of Comet Hyakutake at 80-700 Å: First Detection of Solar Wind Charge Transfer Emissions
Spectra of comet Hyakutake at 80-700 Å observed with a resolving power of 10 reveal for the first time the emission lines of multiple-charged ions that are brought to the comet by the solar wind and

TLDR
If the sample of three comets analyzed so far is typical, the Earth's oceans cannot have been produced by comets alone, they require an additionalsource of water with low D/H, and the highly fractionated neon inthe Earth's atmosphere may indicate the importance of non-icy carriers of volatiles.
On the origin of the carbon atomic ion (C+) in comet 1P/Halley measured from the Giotto Ion Mass spectrometer
More than twenty years after the end of the European Giotto mission, some of the results are still not clearly understood. Indeed we still don’t know what is responsible for the high abundance of the
300-580 Nanometer Long-Slit Spectroscopy of Comet Tabur (C/1996 Q1)
Comets Liller (C/1988 A1) and Tabur (C/1996 Q1) have similar orbits and are thought to have been a single comet until they split at a previous perihelion passage. Long-slit spectra of comet Tabur
Spectroscopic Investigations of Fragment Species in the Coma
The content of the gaseous coma of a comet is dominated by fragment species produced by photolysis of the parent molecules issuing directly from the icy nucleus of the comet. Spectroscopy of these
Using the Ultraviolet and Visible spectrum of Comet 122P/de Vico to Identify the Parent Molecule CS2
A comparison has been made between the unidentified spectral lines of comet 122P/de Vico and observed dispersed fluorescence spectra in the UV and visible region from jet cooled CS2. Twenty-eight
Imaging and spectroscopy of comet C/2001 Q4 (NEAT) at 8.6 AU from the Sun
Comet C/2001 Q4 (NEAT) was observed inbound at an heliocentric distance of 8.6 AU. Broadband filter images in the visible and long slit spectroscopy in the 3500-7000 A range was recorded. No sign of
