Cooling rate effects on the magnetization of volcanic rocks: Some implications for paleointensity determination [PDF]

Geofísica Internacional, 2006
Effects of variation of cooling rate in the acquisition of thermoremanent magnetization (TRM) are analyzed on a suite of volcanic rocks. We use a three-step cooling rate experimental procedure applied at three distinct temperatures of TRM acquisition ...

Magnetic studies of natural goethite samples from Tharsis, Huelva, Spain [PDF]

Geofísica Internacional, 2006
Magnetic properties of goethite have not been widely studied. Natural samples often contain complex mineral mixtures. Material from Tharsis (Huelva, Spain) is studied in order to corroborate the presence of goethite using rock magnetic measurements ...

IDENTIFICATION OF ANTHROPOGENIC MATERIALS IN TOPSOIL FROM THE URBAN AREA OF BANJARMASIN, INDONESIA USING GEOCHEMICAL AND ROCK MAGNETIC PROPERTIES

Rudarsko-geološko-naftni Zbornik
The city of Banjarmasin is located in a peatland and has a tropical climate. Peat areas have their own uniqueness, plus this city is traversed by many tributaries and is very rarely researched, especially in relation to the use of rock magnetism.

Collinear and non-collinear spin ground state of wurtzite CoO

, 2013
Collinear and non-collinear spin structures of wurtzite phase CoO often appearing in nano-sized samples are investigated using first-principles density functional theory calculations. We examined the total energy of several different spin configurations,

Uniaxial-Pressure induced Ferromagnetism of Enhanced Paramagnetic Sr3Ru2O7

, 2004
We report a uniaxial pressure-dependence of magnetism in layered perovskite strontium ruthenate Sr3Ru2O7. By applying a relatively small uniaxial pressure, greater than 0.1 GPa normal to the RuO2 layer, ferromagnetic ordering manifests below 80 K from ...

Magnetic and structural data used to monitor the alloying process of mechanically alloyed Fe80Ni20

Data in Brief, 2018
In the last decades, much attention was given to mechanical alloying as it proved to be a cheap and easy way to produce (even metastable) nanostructured alloys. Especially Fe-Ni alloys have been studied intensely due to their technological and scientific
