Spin excitations in ferromagnetic manganites
, 1998 An effective one-band Hamiltonian for colossal-magnetoresistance (CMR) manganites is constructed and the spin excitations are determined. Fitting the experimental data by the derived spin-wave dispersion gives an e_g -electron hopping amplitude of about ...

Critical Nucleation in Colossal Magnetoresistance
, 2003 Critical exponents have been obtained for a 3D spin particle system. Clusters are formed and system reaches a critical behavior when fragment size distribution follows a power law, as predicted by Fisher Liquid Droplet Model. Also, spontaneous magnetization critical temperature is in agreement with other theoretical studies.

Reconfigurable Magneto‐Optoelectronic Devices for Multidimensional Optical Neural Network
Small Science, Volume 6, Issue 1, January 2026.A reconfigurable magneto‐optoelectronic device with polarization sensitivity is proposed to construct multidimensional optical neural networks (ONNs). By combining 2H‐WSe2 and 2D half‐metal FeCl2 with ideal spin filtering effects, perception of multidimensional optical information is achieved under zero power consumption, which is significantly ...

Anomalous magnetic and transport properties of InSb(Mn) crystals near metal-insulator transition
AIP Advances, 2018 In Mn-doped InSb single crystals an unusual, for nonmagnetic semiconductors, dependence on manganese concentration have been revealed for magnetization, conductivity, magnetoresistance and the Hall effect in the range NMn= (1÷2)×1017cm-3.

Advanced Energy Materials, Volume 15, Issue 37, October 7, 2025.Solar desalination offers a sustainable route to freshwater but is often hindered by low evaporation rates and salt fouling. Here, it is demonstrated that La0.7Sr0.3MnO3 enables efficient photothermal conversion via intra‐band trap states, achieving a high evaporation rate of 3.40 kg m−2 h under one sun.

Small, Volume 21, Issue 39, October 2, 2025.Unscreened high‐density polarons are discovered in a metallic WO3 (001) 2DEG, stabilized by surface oxygen vacancies and c(2 × 2) reconstruction. ARPES and STM/STS reveal polaron formation and ordering, supported by first‐principles calculations. This work opens new avenues for exploring collective polaron phenomena, including bipolaron interactions ...
