The effect of temperature and pressure on the spin state of cobalt ions in La1−xPrxCoO3 compounds
The crystal structure, magnetic susceptibility as a function of temperature χ(T) in the range 5–400 K, and the hydrostatic pressure effect on χ at fixed temperatures T = 78, 150, and 300 K, were
Effects of Temperature and Pressure on the Magnetic Properties of La1–xPrxCoO3
For La1–xPrxCoO3 cobaltites (x = 0, 0.1, 0.2, and 0.3), the dependence of magnetic susceptibility χ(T) is studied in the temperature range 5–400 K. Also, the crystal structure of these cobaltites is
Structural and Magnetic Properties of RMO3 (R = Pr, Nd and M = Fe, Co) Perovskites
In this work, the RMO3 (R = Pr, Nd and M = Fe, Co) perovskites had been synthesized by hydrothermal method. The structural properties of RMO3 prepared samples were investigated by using X-ray
Effect of Multiplicity Fluctuation in Cobalt Ions on Crystal Structure, Magnetic and Electrical Properties of NdCoO3 and SmCoO3
Correlations between the spin state change of cobalt ions and the temperature dependence anomalies of the lattice parameters, magnetic susceptibility, volume thermal expansion coefficient, and electrical resistance have been revealed.
Pressure-induced structural and magnetic phase transitions in La0.75Ba0.25CoO2.9 studied with scattering methods and first-principle calculations
We studied structural and magnetic phase transitions under applied pressure for the doped cobaltite ${\mathrm{La}}_{0.75}{\mathrm{Ba}}_{0.25}{\mathrm{CoO}}_{2.9}$. Neutron and x-ray diffraction
Photoinduced insulator-to-metal transition and coherent acoustic phonon propagation in LaCoO3 thin films explored by femtosecond pump-probe ellipsometry
We have studied ultrafast dynamics of thin films of LaCoO3 and La0.5Sr0.5CoO3 with femtosecond pump-probe ellipsometry in the energy range of 1.6–3.4 eV. We have observed a large pump-induced


Specific features of the magnetic properties of RB4 (R = Ce, Sm and Yb) tetraborides. Effects of pressure
The temperature dependence and the effect of pressure P up to 2 kbar on the magnetic susceptibility χ of the tetraborides SmB4 and YbB4 was studied. For the compound CeB4, the electronic structure
Structural anomalies associated with the electronic and spin transitions in LnCoO3
Abstract.A powder X-ray diffraction study, combined with magnetic susceptibility and electric transport measurements, was performed on a series of LnCoO3 perovskites (Ln = Y, Dy, Gd, Sm, Nd, Pr and
Crystal field and magnetism of Pr3+ and Nd3+ ions in orthorhombic perovskites
Nine parameters characterizing the crystal field of rare-earth ions in the RMO3 perovskites are calculated using a first-principles electronic structure and the Wannier projection and good agreement between the experiment and theory is found.
Low-temperature magnetic behavior of the rare-earth cobaltites GdCoO3 and SmCoO3
The temperature and magnetic field dependences of the static magnetization of the polycrystalline rare-earth cobaltites GdCoO3 and SmCoO3 have been measured. It is shown that, below room temperature,
Preparation and structural study from neutron diffraction data of RCoO3 (R = Pr, Tb, Dy, Ho, Er, Tm, Yb, Lu) perovskites
RCoO3 perovskites (R = Pr, Tb, Dy, Ho, Er, Tm, Yb, Lu) have been prepared in a polycrystalline form by thermal treatment in air (R = Pr, Tb, Dy), under O2 pressure (200 bar) (R = Ho, Er) or moderate
Neutron-scattering study of the spin-state transition and magnetic correlations in La1-xSrxCoO3 (x=0 and 0.08).
The results suggest that the magnetic moments in the doped compound freeze into a spin-glass state at low temperature, indicating that the high-temperature transition is not dominantly magnetic in origin.
