Thermal expansion of Ti-substituted barium hexaferrite [PDF]

Journal of Applied Physics, 2000
Thermal expansion measurements in the range of 20–500 °C were carried out on both poly- and single crystalline samples of the hexagonal magnetoplumbite ferrite with composition BaTiFe11O19. The continuous scanning of the thermal expansion reveals the existence of a λ-type anomaly near the Curie temperature. In contrast to the usual observed anisotropic

Triple‐Stimuli Responsive Soft Robots with Photo‐Programmable Ferriferous Oxide Particle Patterns

Advanced Science, Volume 12, Issue 18, May 15, 2025.
The in situ generation of Fe3O4 nanoparticles in polymer substrate is realized by combining photo‐reduction of Fe3+ to Fe2+ and hydrolytic reaction of the two ions. By spatiotemporal control of UV light irradiation, the distribution of Fe3O4 nanoparticle can be well controlled, which enables the composite with magnetic field, NIR light, and moisture ...
