Summary: In this work, mesoscopic composites of Bi5Ti3FeO15 and BiFeO3 were fabricated to achieve the double consecutive cooling effect. The non-collinear interfacial polarization was proposed as the origin of near room temperature electrocaloric cycling refrigeration. The structure, dielectric capacitance, and ferroelectric polarization of the composite films were analyzed, and the simulation of the mesoscale cooling device showed promising performance for high efficient double cycling refrigeration. Moreover, these results are helpful for understanding the cycling principle of electrocaloric cooling.

Summary: This work proposes a strategy of lattice strain engineering by introducing a (Mg2/3Nb1/3)(3+) ion group into the B site of BiFeO3 films to construct local metal-ion dipoles, breaking through the unfavorable inverse relationship between polarization, bandgap, and leakage. By engineering the lattice strain, a giant remanent polarization of 98 mu C/cm(2), narrower bandgap of 2.56 eV, and significantly decreased leakage current are obtained, resulting in excellent photovoltaic response with high open-circuit voltage and short-circuit current. This study provides an alternative strategy to enhance ferroelectric photovoltaic performances by lattice strain derived from local metal-ion dipoles.

Summary: Recently, researchers have emphasized the high open-circuit voltage of the ferroelectric photovoltaic effect in the Aurivillius-phase perovskite structure. However, the factors limiting this effect are not well understood. By investigating the correlation between polar phase fraction and ferroelectric photovoltage in Sr1-x Ba x Bi4Ti4O15 polycrystalline films, it has been found that the polar phase fraction plays a crucial role in the photocurrent intensity. At the spectrum response peak of 340 nm, the photovoltaic external efficiency can reach 28%.

Summary: This study investigates the magnetic properties and magnetocaloric effects of polycrystalline Bi0.3xLaxCa0.7MnO3 (x = 0, 0.1, 0.2) ceramics, using Raman active modes and phonons to detect charge disorder and local structure distortion. The large magnetocaloric effect is explained by Jahn-Teller distortion and valence perturbations induced by La doping. The study also reveals a connection between complex magnetic phase transition and magnetic entropy in doped manganites, attributed to the temperature-dependent competition between orbital order and charge order.
