Theoretical study of the magnetic moments and anisotropy energy of CoRh nanoparticles
The role of size, structure and chemical order on the magnetic moments and magnetic anisotropy energy (MAE) of CoRh nanoparticles are studied in the framework of a self-consistent real-space tight-binding meth...

Magnetic configurations of isolated and assemblies of iron 30 nm nanocubes studied by electron holography
The magnetic remanent configurations of single and assemblies of crystalline 30 nm Fe nanocubes were studied using off axis electron holography (EH). Experiments were performed on the SACTEM-Toulouse (Tecnai-F...

Anomalously high charge/orbital ordering temperature in Bi0.5Sr0.5MnO3
Neutron/synchrotron diffraction data and magnetic measurements provide direct evidence of charge/orbital ordering at anomalously high temperatures in Bi0.5Sr0.5MnO3, as well as in other (Bi,Sr)MnO3 manganites. We...

Charge modulation and orientational variants in Bi1/3Ca2/3MnO3
We present a neutron/synchrotron diffraction study of the orbital/charge ordering in Bi1/3Ca2/3MnO3. The compound presents a high degree of orthorhombicity, which has permitted us to identify different modulation...

Magnetization measurements of clusters of Mn (II) at low temperature and high magnetic field
The compound under study is a magnetic metal oxyde cluster of Mn(II) encapsulated in between two polyoxymetalate clusters PW9O34, i.e. (Mn4(H2O)2(PW9O34)2)K1020H2O. We measured the magnetization up to 36 T in a l...
