New absolute paleomagnetic intensity data from Cenozoic basalts of Northeast China and exploring rock-magnetic parameters for efficient sample preselection on the Tsunakawa–Shaw paleointensity method

Earth, Planets and Space
Despite being essential in determining absolute paleomagnetic field intensity (API) with high fidelity over Earth science research topics, API determination still suffers little quantitative success.

Paleointensity of the geomagnetic field in the Late Cretaceous and earliest Paleogene obtained from drill cores of the Louisville seamount trail

Geochemistry, Geophysics, Geosystems, 2014
Information on the strength of the geomagnetic field is important for understanding the behavior of the geodynamo. Polarity reversal frequency increases toward the late Cenozoic since the end of the Cretaceous Normal Superchron.

Experimental and computational study of nearly half-metallic V2CoGa [PDF]

AIP Advances
Here, we present the results of a combined computational and experimental study of electronic, magnetic, and structural properties of V2CoGa, a Heusler alloy that exhibits high spin polarization values in an ordered crystal structure.

Evaluation of Magnetic Anisotropy of RE-TM Thermomagnetic Recording Films by the Measurement of Hall Hysteresis Loop Under Obliquely Applied Magnetic Field

IEEE Translation Journal on Magnetics in Japan, 1985
A new method is proposed for checking the magnetic anisotropy of rare earth-transition metal amorphous alloy films for magneto-optical recording. The Hall loop is measured when the magnetic field H is applied to the film at an inclination angle ?(measured relative to the normal of the film), and the relationship between the loop coercivity H c ' and ?,

A thermomagnetic analysis of rocks (20-700 degrees C.) : the design and construction of measuring apparatus, and its application to rocks from the Whiteshell area

, 1970
As a preliminary study, relating to the regional magnetic anomalies in Manitoba and Northwestern Ontario, a reconnaissance sampling survey has been made over the flank of a regional anomaly in the Whiteshell area of Southeastern Manitoba. Thermomagnetic curves and Curie transition temperatures have been determined for 70 samples over the 14 mile ...

Apparatus for measuring transient processes during thermomagnetic recording

Review of Scientific Instruments, 1974
An apparatus is described for measuring thermal and magnetization dynamics during thermomagnetic writing of information onto magneto-optic films. By probing various regions of the reversed spot, the spatial dynamics of bit formation can be reconstructed.
