Response of Ag Thick Film Microstripline due to Superstrate Strontium Substituted Bismuth Manganites [PDF]

Журнал нано- та електронної фізики, 2014
The purpose of this paper is to describe the use of strontium-substituted bismuth manganites bulk ceramic superstrate on Ag thick film microstripline, to modify its response and measure complex permittivity as a function of strontium.

Zero Temperature Insulator-Metal Transition in Doped Manganites [PDF]

, 2003
We study the transition at T=0 from a ferromagnetic insulating to a ferromagnetic metallic phase in manganites as a function of hole doping using an effective low-energy model Hamiltonian proposed by us recently. The model incorporates the quantum nature

Impact of Alkali Ions Codoping on Magnetic Properties of La_0.9A_0.1Mn_0.9Co_0.1O₃ (A: Li, K, Na) Powders and Ceramics

Applied Sciences, 2020
The aim of the work was to check how the introduction of alkali and cobalt ions into a manganese structure can affect the structural disorder and, in consequence, lead to the changes (improvements) of magnetic properties.

Surface phase separation in nanosized charge-ordered manganites

, 2007
Recent experiments showed that the robust charge-ordering in manganites can be weakened by reducing the grain size down to nanoscale. Weak ferromagnetism was evidenced in both nanoparticles and nanowires of charge-ordered manganites.

The Influence of Pressure on the Formation of FM/AF Configurations in LSMO Films: A Monte Carlo Approach

Computation, 2020
In this work, Monte Carlo simulations of magnetic properties of thin films, including the influence of an external pressure, are presented. These simulations were developed using a Hamiltonian composed by terms that represent the exchange interaction ...

Charge Ordering in Half-Doped Manganites: Weak Charge Disproportion and Leading Mechanisms

, 2010
The apparent contradiction between the recently observed weak charge disproportion and the traditional Mn$^{3+}$/Mn$^{4+}$ picture of the charge-orbital orders in half-doped manganites is resolved by a novel Wannier states analysis of the LDA$+U ...

The charge ordered state in half-doped Bi-based manganites studied by $^{17}$O and $^{209}$Bi NMR

, 2005
We present a $^{209}$Bi and $^{17}$O NMR study of the Mn electron spin correlations developed in the charge ordered state of Bi$_{0.5}$Sr$_{0.5}$MnO$_{3}$ and Bi$_{0.5}$Ca$_{0.5}$MnO$_{3}$.

Stepwise Reduction of Ruthenium and Growth of Magnetic Structure During Hydrothermal Crystallisation of SrRu2O6 from KRuO4

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
In situ neutron powder diffraction data collected while heating the Ru(VII) reagent KRuO4 in the presence of aqueous Sr2+ reveal the crystallisation of a Ru(VI) oxyhydroxide before the expected Ru(V) oxide; at the same time evolution of antiferromagnetism in the final SrRu2O6 product follows the growth of its crystal structure.
