A review on rock magnetism

Material Science & Engineering International Journal, 2018
Crustal rocks have a magnetic memory that may endure for millions or even billions of years due to composition of iron oxides The secret behind that permanence lies in the high temperatures to which the minerals were exposed near their Curie temperatures of several hundred degrees Celsius while cooling in Earth rsquo s magnetic field and in the ...

The importance of clays in speleothem magnetic remanence acquisition

Scientific Reports
Speleothems are promising recorders of paleosecular variation of the Earth’s magnetic field, but ambiguities remain about the physical processes active during remanence acquisition.

A detailed paleomagnetic and rock-magnetic investigation of the Matuyama-Bruhnes geomagnetic reversal recorded in tephra-paleosol sequence of Tlaxcala(Central Mexico)

Frontiers in Earth Science, 2015
Geomagnetic reversals are global phenomena, for about 50 years the paleomagnetists attempted to acquire as many detailed records as possible using the magnetic memory of sediments and lava flows.

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

Molecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

Magnetic Difference Between Deep and Surface Soil Within an Agricultural Area in Southern China: Implications for Magnetic Mineral Transformation During Pedogenic Process Under Subtropical Climate

Earth and Space Science, 2020
Mineral magnetism is proved as a sensitive method of pedogenesis by numerous studies. However, formation pathways of magnetic minerals and subsequent magnetic response are quite different under different climate.

Giant Magnetic Coercivity Driven by Spin‐Bag Ferromagnetism in Epitaxial Sr3YCo4O10+δ Films with Engineered 2D Oxygen Vacancy Ordering

Advanced Functional Materials, EarlyView.
A giant magnetic coercivity and a vertical shift of hysteresis loops are demonstrated in Sr3YCo4O10+δ epitaxial films. The hard magnetic behavior originates from ferromagnetic spin bags stabilized within a long‐range ordered oxygen‐vacancy structure.
