Stable suspensions of ferroelectric BaTiO3-particles
Abstract Stable suspensions of small BaTiO 3 -particles in hydrocarbon carrier liquids were produced by long milling process. It is shown that particles with an average radius of about 10nm carry aExpand

Bond-valence analysis on the structural effects in magnetoresistive manganese perovskites
For the perovskites that show colossal-magnetoresistance (CMR) behaviour, we use the global instability index, R1, as a measure of the influence of the static lattice effects on the magnetic andExpand

Crystal structure and magnetic ordering of the LaCo1?xFexO3 system
The LaCo1−xFexO3 compounds have been investigated by means of neutron powder diffraction (NPD), x-ray powder diffraction (XPD) and magnetization measurements. The NPD and XPD patterns wereExpand

COP of cooling cycles around the AF–F transition in FeRh based on experimental data
Abstract By the heat capacity of the FeRh alloy when heating in the AF–F transition region in zero magnetic field and the change in the temperature of the alloy when the transition is adiabaticallyExpand

Magnetic properties of alloys in the system MnSb–MnBi
The magnetic moment of compounds in the quasibinary system MnSb–MnBi has been investigated as a function of temperature in the range from 80 to 750 K for ten ratios of Bi/Sb. The hexagonal NiAs-typeExpand
