Electric and magnetic properties of PMMA/manganite composites

Mostrar todas las versiones(2)

We present the synthesis and characterization of the La2/3Sr1/3MnO3 manganite in the form of tapes using polymethyl methacrylate (PMMA) as binder. We have studied their electric and magnetic properties as a function of temperature and magnetic field. The magnetization results have been shown to be d...
