Relaxation of thermal-remanent magnetization and isothermal remanent magnetization of spin glass in Cd& „Mn„Te diluted magnetic semiconductors have been studied at different conditions. Magnetization relaxation can be described by a power-law decay, M(t) =Mpt (f & to and to=2 s) with small values of a or a logarithmic decay M(t}=MD(1—a lnt) (t & to and to=2 s). Temperature and applied magnetic-...

Non-equilibrium dynamics in a Ag(Mn) spin glass are investigated by measurements of the temperature dependence of the remanent magnetization. Using specific cooling protocols before recording the thermo-or isothermal remanent magnetizations on reheating , it is found that the measured curves effectively disclose non-equilibrium spin glass characteristics such as aging and memory phenomena as we...

This paper presents a magnetization modeling method combined with material sensitivity information to identify the unknown magnetization distribution of a hull and improve the accuracy of the predicted fields. First, based on the magnetization modeling, the hull surface was divided into three-dimensional sheet elements, where the individual remanent magnetization was assumed to be constant. For...

To investigate the acquisition mechanism of high and stable natural remanent magnetization (NRM) in rocks of the Russell Belt, Adirondack Mountains, New York, we examined the exsolution microstructures and compositions of magnetic minerals using three samples with different magnetic properties. The samples contain titanohematite with ilmenite lamellae, end-member hematite without lamellae and r...
