Numerical analysis of thermomagnetic generators

Journal of Applied Physics, 1984
Thermomagnetic generators allow direct conversion of heat energy to electrical energy. Temperature cycling about or near the Curie temperature causes changes in magnetization, resulting in time variant magnetic flux and induced voltage in a surrounding conductor.

THERMOMAGNETIC ANALYSIS OF SEMICONDUCTOR DEVICES USING TRENDY

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 1994
This paper describes the two‐dimensional numerical solution of the system of partial differential equations governing the carrier and heat transport in a semiconductor structure in the presence of a magnetic field. The model is based on a thermodynamic approach and it was implemented in the thermomagnetic module of 2D process/device simulator TRENDY ...

Application of thermomagnetic analysis to picroilmenite investigation

Russian Geology and Geophysics, 2009
Abstract Picroilmenite samples from five kimberlite pipes of the Yakutian kimberlite province have been studied. Point microprobe analyses of two mutually perpendicular profiles of each sample were carried out to study the compositional inhomogeneity of picroilmenite. Thermomagnetic curves were also recorded for each sample.

A scaling analysis to characterize thermomagnetic convection

International Journal of Heat and Mass Transfer, 2005
Abstract Thermomagnetic convection is characterized using scaling arguments. We consider a square enclosure filled with a ferrofluid that is under the influence of an external magnetic field created by a line dipole. The height-averaged Nusselt number scales with the magnetic Rayleigh number as Nu ∼ Ra m 0 . 25 .

THERMOMAGNETIC ANALYSIS AND ORE GENESIS

Canadian Journal of Earth Sciences, 1967
The potential of rock magnetism in studies on the genesis of ore deposits is examined. It is suggested that techniques based on magnetic properties other than the direction of the stable part of the natural remanent magnetization might prove usefully applicable.

Electron Diffraction for the Thermomagnetic Analysis of a Ferromagnetic

Crystal Research and Technology, 1982
AbstractA thermomagnetic analysis of ferromagnetic invar was made by the diffraction procedure utilizing the electorns accelerated over 200 keV. An electron beam served for heating the specimen by electron bombardment. An empirical formula has been proposed for analying the observations.

Magnetic and thermomagnetic analysis of metal evaporated tape

Journal of Applied Physics, 1991
Metal evaporated (ME) tape is being developed as an advanced medium for high-density magnetic tape recording. It is produced by evaporation in an oxygen atmosphere, and consists of very small Co and CoNi crystallites intermingled with oxides of Co and Ni.

Thermomagnetic Analysis in Archaeometry: The Akhenaten Temple Project

Analytical Letters, 1983
Abstract Saturation magnetization (JS) as a function of temerature at 10−3 torr and atmospheric pressure has been measured for a series of materials obtained from the Akhenaten Temple Site, East Karnak, Egypt. The analytical problem lies in the determination of iron oxide speciation with respect to firing conditions. These thermomagnetic, (JS-T) curves

Thermomagnetic analysis of soft magnetic nanocrystalline alloys

Journal of Alloys and Compounds, 2017
Abstract In the paper, the crystallization process of Fe 95.5− x − y (Co, Ni) x Cu 1 Nb 2 Mo 1.5 (Si, B) y alloys has been investigated using a thermomagnetic analysis. In the course of heating, continuous measurements of temperature and initial magnetic permeability were performed.
