Summary: Scheelite-type HoCrO4, prepared via pressure treatment of the ambient-pressure zircon-type precursor phase, exhibits a long-range antiferromagnetic phase and can be induced into a metamagnetic state with a moderate magnetic field. It shows a considerable linear magnetoelectric effect and a sharp increase in electric polarization near the critical field of the metamagnetic transition. However, ferromagnetism and ferroelectricity rarely coexist under higher magnetic fields in scheelite-type HoCrO4. The magnetic field also plays a significant role in the longitudinal constriction and magnetostrictive effect of HoCrO4.

Summary: This study investigates the low-frequency magnetoelectric (ME) effects in heterostructures consisting of a layer of antiferromagnetic hematite & alpha;-Fe2O3 crystal with easy-plane anisotropy and a piezoelectric layer. The results show that the frequency tuning of the hematite crystal is linearly related to the increase in the bias field, reaching up to 37%. The frequency tuning of the hematite-PVDF heterostructure is 24% with a ME coefficient of 58 mV/(Oe & BULL;cm). The frequency tuning of the hematite-piezoceramic heterostructure is 4.4% with a ME coefficient of 4.8 V/(Oe & BULL;cm). Additionally, efficient generation of the second voltage harmonic is observed in the hematite-piezoceramic heterostructure.

Summary: The authors previously introduced a novel magnetoelectric (ME) composite configuration called distributed disc structured (DDS) configuration, which can operate at high temperatures without epoxy. However, a topological study revealed that the absence of epoxy in the DDS composites resulted in material discontinuity and voids at the magnetostrictive/piezoelectric interface, negatively impacting the ME response. In this study, epoxy was used to fill the voids in the DDS composites, resulting in a remarkable improvement in the quasi-static and resonant ME measurements compared to epoxy-free counterparts.

Summary: PVDF-HFP films incorporating different types of imidazolium ionic liquids with different magnetic anions and imidazolium cation chain lengths have been developed for humidity-sensing applications. The IL/PVDF-HFP composites exhibit a porous structure independently of the IL anion type and cation chain length. The inclusion of ILs induces polymer crystallization into the electroactive beta phase, with the most noticeable increase observed for PVDF-HFP/[Bmim][FeCl4]. The hybrid samples show a decrease in thermal stability and yield strength, with PVDF-HFP/[Bmim]2[Co(SCN)4] samples experiencing the most significant decrease. PVDF-HFP/[Bmim]2[Co-(SCN)4] and PVDF-HFP/[Bmim][FeCl4] composites display the highest magnetization. The PVDF-HFP/[Bmim]2[CoCl4] composite exhibits the highest relative humidity sensing response. The developed IL/polymer composites show potential for humidity sensing applications.
