Relaxation Phenomena of MgZn Ferrites

Relaxation phenomena during non-equilibrium growth

Interaction effects and energy barrier distribution on the magnetic relaxation of nanocrystalline hexagonal ferrites

The static and dynamic magnetic properties of nanocrystalline BaFe10.4Co0.8Ti0.8O19 M -type doped barium ferrite were studied in detail to clarify the effect of interactions on the magnetic relaxation of an assembly of small particles. The logarithmic approximation was unable to account for the magnetic relaxation of the sample. Interaction effects were analyzed from the low-field susceptibilit...

Ordering phenomena during the structural relaxation of sputtered Ni 24Zr76

2014 The structural evolution of an amorphous metallic alloy of composition Ni24Zr76 produced by sputtering was studied at temperatures below the onset of crystallization by means of electrical resistance and shear modulus measurements. Analysis of the variations observed for these two physical parameters leads to the conclusion that two distinct processes are operative in the structural relaxa...

Modeling of capacitance relaxation phenomena in a malignant membrane

Electrical Impedance scanning (EIS) is a new technique in which moderate variations in capacitance values are reflected by the cells of various type of normal membrane. The malignant membrane, in contrast, in EIS demonstrates significant capacitance relaxation phenomena concomitant with α dispersion in the low audio frequency range. The author has endeavored to establish the above stated phenom...

Oscillators and relaxation phenomena in Pleistocene climate theory

Ice sheets appeared in the northern hemisphere around 3 Ma (million years) ago and glacial-interglacial cycles have paced Earth's climate since then. Superimposed on these long glacial cycles comes an intricate pattern of millennial and sub-millennial variability, including Dansgaard-Oeschger and Heinrich events. There are numerous theories about these oscillations. Here, we review a number of ...
