Dramatic enhancement of the saturation magnetization of a sol-gel synthesized Y 3 Fe 5 O 12 by a mechanical pressing process

Size-dependent optical and thermochromic properties of Sm3Fe5O12

“…The high-density surface generates extra surface energy and promotes the oxidation reaction. 43 Fig. 7 presents the room-temperature UV-vis-NIR diffuse reectance and absorption (i.e., Kubelka-Munk transformed reectance) spectra of Sm 3 Fe 5 O 12 synthesized with different particle size in the range of 200-1200 nm.…”

Solution-Processed Ferrimagnetic Insulator Thin Film for the Microelectronic Spin Seebeck Energy Conversion

“…The as-grown YIG film typically undergoes phase transformation with annealing temperature of 600−1000 °C depending on the details of environment. 31,36,40 Our results showed spin-coated samples with annealing temperature over 800 °C become crystallized. The diffraction peaks correspond to (400), (420), and (422) of the YIG film.…”

Surface radio-mineralisation mediates chelate-free radiolabelling of iron oxide nanoparticles

“…Fe environments were largely unchanged after In/Zr treatment, with only 0.1 eV variation across the three samples in Fe 2p scans, in good agreement with the Mössbauer spectra. The Fe 2p 3/2 values of 710.6 (AA maghemite), 710.7 (SA magnetite), and 710.3 eV (Y 3 Fe 5 O 12 ) are indicative of γ-Fe 2 O 3 (710.6, 710.7 eV) and Y 3 Fe 5 O 12 (710.3 eV) respectively 21,22. There was also little variation within the Y 3 Fe 5 O 12 samples, with a single environment, and a variation in the Y 3d 5/2 range of 157.0–157.3 eV displayed, similar to that observed in Y 2 O 3 23…”
