The effects of Al ion doping on the Mn site were studied for the colossal magnetoresistance material La0.67Ca0.33MnO3. It is found that the volume of the crysta
The amorphous TbCo/Cr films with perpendicular magneto-anisotropy were prepared by nonbiased r.f magnetron sputtering and the effects of Cr underlayer on the ma
Gd2O3∶Eu3+ phosphors were prepared by urea homogeneous precipitation with different surfactant and sol-gel method. XRD patterns show that all the obtained samp
