Remanent 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 کاملRemanent 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 کاملMagnetization of the lunar crust
[1] Magnetic fields measured by the satellite Lunar Prospector show large scale features resulting from remanently magnetized crust. Vector data synthesized at satellite altitude from a spherical harmonic model of the lunar crustal field, and the radial component of the magnetometer data, have been used to produce spatially continuous global magnetization models for the lunar crust. The magneti...
متن کاملEffect of hydrostatic pressure on viscous remanent magnetization in magnetitebearing specimens
Rocks at depth in the crust acquire a viscous (i.e., time-dependent) magnetization under the pressure-temperature conditions at which they reside. There have been numerous• studies on the effect of temperature on viscous magnetization but little work has been performed on the effect of hydrostatic pressure. We have studied viscous remanent magnetization at 22øC in a 0.1 mT field at 0.1 and 100 ...
