Effect of texture dispersion on the effective biaxial modulus of cubic polycrystalline films

“…magnetoelectric coupling factors were of strong dependence on the texture dispersion degree [28][29][30]. However, to our knowledge, there are few detailed theoretical studies on M eff of cubic polycrystalline films with texture dispersion.…”

“…The measurement of pole figures is possibly to provide the information of entire orientation distribution function [33]. X-ray rocking curves (v scans) are usually believed to give a direct measure of grain out-of-plane alignment, determine the FWHM, estimate u distribution, and further deduce the texture about f [29,33]. When the treatments are appropriate, FWHMu and FWHMf relating to a and b, respectively, can be expressed as…”

“…In the present paper, it is assumed that the distributions of angles u and f are coupled and the corresponding expression Wðu; f; cÞ / e ÀðuÀucÞ 2 =2a 2 e ÀðfÀf c Þ 2 =2b 2 is yielded based on the definition of ODF. Analogical treatment was adopted by Ruglovsky who modeled the function relation between the effective electromechanical constants and the biaxial crystallographic texture in polycrystalline films by assuming Gaussian distribution of two Euler angles about the perfect orientation [29]. Using Eq.…”
