ON THE MAGNETORESISTANCE OF COBALT BASED MAGNETORESISTIVE STRUCTURES
Journal Title: Journal of Science And Arts - Year 2011, Vol 17, Issue 4
Abstract
We characterize Co-based metallic multilayers by an exponential model of response of magnetoresistance to applied magnetic field. The magnetic coefficient (k) is found to be dependent on interface roughness and is (tesla)-1 for Co(10Å)/Cu(10Å)|15 at 2GPa pressure [9] and Co(2nm)/Cu(1nm)|300 [16]. Our analysis attributes this to influence of pressure on the microstructure of interfaces.

A HISTORY OF ZERO
One of the commonest questions which the readers of this archive ask is: Who discovered zero? Why then have we not written an article on zero as one of the first in the archive? The reason is basically because of the dif...
NEUTRON ACTIVATION METHOD APPLIED IN THE STUDY OF TRANSFER EFFICIENCIES OF MINOR ELEMENTS DURING STEELMAKING
Neutron activation analysis was applied to investigate the behaviour of some metallurgical materials (pig iron, scrap, lime, LD steel, refining slag, sludge, ferroalloys, aluminum, coke, deoxidized steel, final slag) inv...
EXPLICIT APPLICATION OF SWANEPOEL’S METHOD<br /> FOR THE ANALYSIS OF Sb<sub>2</sub>O<sub>3</sub> FILMS
Swanepoel’s method can be applied successfully for the determination of essential optical parameters for films exhibiting interference pattern-type of optical transmission spectra, such those made of antimony trioxide de...
THE EQUIVALENCE BETWEEN SOME DIFFERENTIAL EQUATIONS
The classical method for solving Riccati equations uses a change which leads to a first order linear equation. We give here a new method of the variation of constants.
