Rybnicek et al. proposed the binary and ternary blends from three materials including PMMA, PC, and ABS.
Experimental Set-Up and Method Materials, Injection Molding Machine, and Mechanical Measurement Polymer materials were supplied in pellet form.
It is obvious that the increase in melt temperature results in a degradation of PMMA materials in the blend.
This investigation provides a clear understanding for fabricating optical molded elements of materials PMMA/PC blends.

Introduction
Multiferroics are the multifunctional materials which exhibits coexistence of at least two of ferroelectricity, ferromagnetism and ferroelasticity in a certain temperature range[1].
Especially for the new information storage, the magnetoelectric coupling in multiferroics can overcome the effect of fatigue properties in polarization reversion of multiferroic materials, and provide more flexibility and freedom of structural design[2-3].
Raman spectroscopy has been demonstrated to be a very useful technique in studying phase transitional characteristics and local structure modulation in ferroelectric materials.
