Advancing Energy Materials by In Situ Atomic Scale Methods

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Magnetotransport properties of La$_{1-x}$Ca$_x$MnO$_3$ (0.52 $\leq x \leq$ 0.75): signature of phase coexistence

open access: yes, 2017
We report the temperature and magnetic field dependence of transport properties in epitaxial films of the manganite La$_{1-x}$Ca$_{x}$MnO$_{3}$ in the overdoped region of the phase diagram for $x > 0.5$, where a charge--ordered (CO) and an ...

Structural, Superconducting and Magnetic Properties of Oxygen‐Annealed Fe1+yTe Thin Films

open access: yesAdvanced Physics Research, EarlyView.
FeTe:Ox films exhibit exchange bias below their Néel temperatures, which coexists with superconductivity. STEM analysis reveals the structural changes induced by oxygen treatment. DFT calculations indicate that interstitial oxygen suppresses antiferromagnetism and promotes superconductivity.

Synthetic Engineering of Manganese Oxide–Carbon Nanocomposites for Maximized Metal Utilization in Supercapacitors

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐pot metal–ammonia synthesis enables uniform Mn2O3 nanoparticle deposition on activated carbon, yielding composites with excellent electrochemical performance in supercapacitors. The method maximizes manganese utilization, eliminates toxic solvents, and achieves 34% of the theoretical maximum capacitance, significantly outperforming existing Mn–C ...

Ultrafast Terahertz Field Control of the Emergent Magnetic and Electronic Interactions at Oxide Interfaces

open access: yesAdvanced Materials, Volume 38, Issue 8, 6 February 2026.
Intense single‐cycle THz electric‐field pulses enable ultrafast control of emergent electronic and magnetic states at LaNiO3/CaMnO3 interfaces. Combined X‐ray and optical probes reveal sub‐picosecond demagnetization driven by spin‐polarized currents and slower magnetoelastic dynamics linked to spin–lattice coupling.

Effects of lattice distortion and Jahn–Teller coupling on the magnetoresistance of La0.7Ca0.3MnO3 and La0.5Ca0.5CoO3 epitaxial films [PDF]

open access: yes, 1997
Studies of La0.7Ca0.3MnO3 epitaxial films on substrates with a range of lattice constants reveal two dominant contributions to the occurrence of colossal negative magnetoresistance (CMR) in these manganites: at high temperatures (T → TC, TC being the ...

Magnetic Phases of Electron-Doped Manganites

open access: yes, 2000
We study the anisotropic magnetic structures exhibited by electron-doped manganites using a model which incorporates the double-exchange between orbital ly degenerate $e_{g}$ electrons and the super-exchange between $t_{2g}$ electrons with realistic ...
