Dynamic relaxation of magnetic clusters in a ferromagnetic (Ga,Mn)As epilayer [PDF]

open access: yes, 2006
A new scenario of the mechanism of intriguing ferromagnetic properties in Mn-doped magnetic semiconductor (Ga,Mn)As is examined in detail. We find that magnetic features seen in zero-field cooled and field cooled magnetizations are not interpreted with a

Broadband Dielectric Properties and Temperature Effects of Silicone Gel for IGBT Device Encapsulation

open access: yesZhongguo dianli, 2020
Silicone gel materials are used as packaging material for IGBT devices. Under the operating conditions, the devices are subjected to a repetitive on-off voltage which corresponds to the wide spectrum, and the device loss will cause temperature rise.

Multiplicative stochastic heat equations on the whole space [PDF]

open access: yes, 2015
We carry out the construction of some ill-posed multiplicative stochastic heat equations on unbounded domains. The two main equations our result covers are, on the one hand the parabolic Anderson model on R³, and on the other hand the KPZ equation on R ...

Determination of a Dimensionless Fluctuation Coefficient Using Electrochemical Impedance Spectroscopy

open access: yesInternational Journal of Electrochemical Science, 2019
Using the Randles circuit model, we determined that, for the impedance to fall on a straight line in a Cole-Cole plot, a dimensionless fluctuation coefficient that represents the quantity of the fluctuation in ion concentration near an electrode must be ...

Computation of Analytical Derivatives for Airborne TEM Inversion Using a Cole–Cole Parameterization Based on the Current Waveform of the Transmitter

open access: yesSensors, 2022
Airborne transient electromagnetic (ATEM) technology is a technique often used in mineral exploration and geological mapping. Due to inductive polarization (IP) phenomena, the ATEM response curve often shows a negative response or declines rapidly to the
