Tensile-strained epitaxial La0.67Ba0.33MnO3(LBMO)film has been prepared by magnetron sputtering technique on(001)oriented spinel MgAl2O4substrate.The transport and magnetic measurements give an insulator-metal transit...
Ⅰ. Because of the influence of the change in distance between ions on the exchange interaction,there exists coupling between spin-waves and phonons in magnetically ordered materials.Most of nonmetallic antiferromagne...
