Remanent magnetization in CoO antiferromagnetic nanoparticles
We report a study on the remanent magnetization Mr induced by field cooling across the ordering temperature TN in antiferromagnetic CoO nanoparticles with different sizes. The nanoparticles are composed by a structurally and magnetically ordered core and a structurally ordered and magnetically disordered shell with a thickness of about 2 nm. The ordered core has cell parameters, moments directi...
متن کاملTwo-Dimensional Compact Inversion of Magnetic Data in the Presence of Remanent Magnetization
Remnant magnetization causes a change in the direction and intensity of the magnetization vector. If inversion is performed regardless of remnance, in some cases it may have unreliable and misleading results. For inversion with respect to remnant magnetization, several solutions have been proposed so far, one of which is to convert the data of total magnetic field into data that is independent ...
متن کاملRemanent magnetization of fine particles
2014 A brief review is given of some calculations of the remanent magnetization of fine particles. The remanence after previous saturation has been calculated for a number of different types of anisotropy. A discussion is also given of remanence curves attained after application of D. C. or A. C. fields, and relations between such curves are pointed out. LE JOURNAL DE PIIYSIQUE ET LE RADIUM TOM...
متن کاملVector Angle of Remanent Magnetization
-A simple method for estimating the remanent magnetization vector angle (e) is introduced. By using this method, the orientation effects of Ba-ferrite FDs on the effective vector angle for the remanent magnetization and on recording characteristics were investigated. The resul ts show that the angle e depends on perpendicular squareness ratio (S~) and is independent from Hc. Also, the larger th...
متن کاملCoexistence of antiferromagnetic and ferromagnetic orders at remanent state in epitaxial multiferroic Bi2FeCrO6 nanostructures.
We report the local electronic and magnetic properties of Bi(2)FeCrO(6) nanostructures by element-specific polarized x-ray techniques. Sizable magnetic ordering in the remanent state is observed at room temperature for both Fe and Cr ions. The Bi(2)FeCrO(6) system offers an example of d(5)-d(3) magnetic superexchange interaction with a magnetic order for both Fe and Cr, which are both formally ...
