Influence of magnetic field on paramagnetic-ferromagnetic transition in La$_{1-x}$Ca$_{x}$MnO$_{3}$ ($x\approx 0.25$) crystal: ultrasonic and transport studies

open access: yes, 2006
The ultrasonic properties of La$_{1-x}$Ca$_{x}$MnO$_{3}$ ($x\approx 0.25$) with the Curie temperature $T_C$ about 200 K are studied. Temperature dependences of longitudinal and transverse sound velocities were measured in zero magnetic field and for ...

Metastable Ordered Mesoporous h‐LuFeO3 Thin Films Prepared by Soft‐Templating: Optical, Electronic, and Magnetic Properties

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 2, 20 January 2026.
An intriguing design concept for the preparation of metastable mesoporous h‐LuFeO3 thin films and powders by soft‐templating is presented. The hexagonal rather than the orthorhombic phase is formed due to the presence of a polymer structure‐directing agent in the synthesis.

Soft spin waves in the low temperature thermodynamics of Pr_{0.7}Ca_{0.3}MnO_{3}

open access: yes, 2000
We present a detailed magnetothermal study of Pr(0.7)Ca(0.3)MnO(3), a perovskite manganite in which an insulator-metal transition can be driven by magnetic field, but also by pressure, visible light, x-rays, or high currents.

Dynamics of electronic phase separation at the laser-induced insulator-metal transition in (La_{0.6}Pr_{0.4})_{0.7}Ca_{0.3}MnO_{3}

open access: yesPhysical Review Research
Ultrafast optical excitations allow creating new metastable and hidden states in quantum materials. However, the fundamental material properties required to support new emergent order are largely unknown.

Orbital Ordering and Resonant X-ray Scattering in Layered Manganites

open access: yes, 1999
In layered manganites with orbital and charge orderings, the degeneracy of the Mn $4p$ orbitals as well as the $3d$ ones is lifted by the effects of the $4p$ bands and the local Coulomb interactions.

Variations in Local Oscillatory Dynamics in Strained LSMO Thin Films, Observed in Non Equilibrium Transport Studies, for Brain Networks

open access: yesAdvanced Electronic Materials, Volume 12, Issue 2, 21 January 2026.
Dynamics of neuron‐like oscillators on an epitaxial film of strained LSMO on a textured LAO substrate. The temperature variation of the oscillations are a consequence of orbital hybridization effects. The oscillation frequencies correspond to the frequencies that characterize brain waves.

Dielectric behavior of La1-xCaxMnO3 (0.4 ≤ x ≤ 0.5)

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2006
In this work the dielectric behavior of semiconducting La-manganites in an intermediate Ca-doping regime is studied. Ceramic samples were prepared by conventional solid-state reaction, using elemental oxides as starting reactants.

Magnon Damping by magnon-phonon coupling in Manganese Perovskites

open access: yes, 1999
Inelastic neutron scattering was used to systematically investigate the spin-wave excitations (magnons) in ferromagnetic manganese perovskites. In spite of the large differences in the Curie temperatures ($T_C$s) of different manganites, their low ...

Spin Matters: A Multidisciplinary Roadmap to Understanding Spin Effects in Oxygen Evolution Reaction During Water Electrolysis

open access: yesAdvanced Energy Materials, Volume 16, Issue 4, 28 January 2026.
This roadmap offers a forward‐looking perspective on spin enhancement in the oxygen evolution reaction. It highlights how combining systematic experiments, advanced computational modeling, and novel magnetic, chiral, or hybrid materials can deepen the understanding of spin‐dependent catalytic mechanisms.
