Hematite is a canted antiferromagnet with reddish color that occurs widely on Earth and
Mars. Identification and quantification of hematite is conveniently achieved through its …

An understanding of the effects of hypervelocity impacts on the magnetization of natural
samples is required for interpreting paleomagnetic records of meteorites, lunar rocks, and …

We present a description of opaque minerals, opaque mineral compositions, magnetic
properties, and paleomagnetic record of the Tissint heavily shocked olivine‐phyric …

The 23km-diameter well-preserved Haughton impact structure shows a rather unique
combination of a positive magnetic anomaly with a negative gravity anomaly over the center …

Shock experiments with pressures ranging from 3 to 30 GPa have been conducted on a
mixed assemblage of hexagonal and monoclinic pyrrhotite. All samples were studied with …

River sediment is comprised of complex mineral systems composed by different kinds of
organic and inorganic matter, and thus, is difficult to characterize. Besides, some standard …

Abstract Monoclinic pyrrhotite (Fe7S8) owes its ferrimagnetism to an ordered array of Fe
vacancies. Its magnetic properties change markedly around 30 K, in what is known as the …

Pyrrhotite Fe 7 S 8 provides an example of exceptionally strong magnetoelastic coupling
through pinning of ferromagnetic domains by ferroelastic twins. Using direct imaging of …

为快速鉴定高温高压(HPHT) 合成钻石, 前人已开展了系统的发光特征和谱学特征研究,
但对比性分析较少, 且对电学性质和磁学性质关注不多. 本文结合常规宝石学观察 …

Magnetite is an abundant magnetic mineral that commonly records the ancient magnetic
field in a wide variety of rock types. When cooled below≈ 124 K, magnetite undergoes a …
