Phase transitions in La0.73Ca0.27Mn1-xCuxO3 (0 < X < 0.19)
We have performed resistivity measurements as a function of temperature, with and without an external magnetic field. Magnetization measurements are also done as a function of temperature M(T) as well as a function of an external magnetic field M(H) for La0.73Ca0.27Mn1-xCuxO3compounds with 0...

Studi teoretik pengaruh vakansi oksigen terhadap kemagnetan dan transpor muatan pada fe3o4 = Theoretical study of the effect of oxygen vacancies on magnetism and charge transport of fE3O4 / Angga Dito Fauzi
ABSTRAK
Fe3O4 merupakan material ferrimagnetik paruh logam dengan TC 860 K yang menunjukkan transisi logam-isolator MIT pada 120 K. Dalam bentuk bulk, magnetisasi saturasi material tersebut adalah 0.6 Tesla 471 emu/cm3 . Penelitian eksperimental terbaru telah menunjukkan bahwa magnetisasi saturasi dari lapisan tipis nano-Fe3O4 dapat mencapai 760 emu/cm3 yang diakibatkan oleh...

Theoretical study of the dependence of single impurity anderson model on various parameters within distributional exact diagonalization method = Studi teoretik kebergantungan single impurity anderson model terhadap berbagai parameter dengan metode distributional exact diagonalization
ABSTRACT
One of the simple models to address quantum many body effects in materials with impurities is Anderson Impurity Model. It describes a system consisting of non interacting conduction electrons having hybridization with a localized orbital with strong electron electron interaction at a particular site. This model has been proven successful...

Calculation of optical conductivity of anderson impurity model for various model parameters = Kalkulasi dari konduktivitas optis dari model impuritas anderson untuk berbagai model parameter
ABSTRACT
The complex and fascinating properties of a material often arises due to interactions among electrons as well as between electrons and other constituents of the material. A common model to describe the strongly correlated electronic system with strong on site Coulomb interaction is Hubbard model. It is usually aimed to...
