Piezomagnetic ε-Fe2O3 crystals
New synthesis method to produce ε -Fe2O3 nanoparticles for magnetic memories or wireless communication devices
- Market need
-
ε -Fe2O3 presents a large magnetic anisotropy that makes it interesting for technological applications related to magnetic memories and to the development of self-biased non-reciprocal devices which are appealing for the forthcoming generations of wireless communications.
ε -Fe2O3 should be above 25 nm to retain the magnetization. There are several methods to prepare these nanoparticles, but none of them is scalable, making impossible an industrial application.
- Proposed solution
-
Our new method allows the synthesis of piezomagnetic ε -Fe2O3 nanoparticles of sizes above 25 nm. The nanoparticles can be used for the manufacturing of magnetic memories or wireless communication devices as self-biased non-reciprocal devices, such as miniaturized circulators for high-frequency (above 100 GHz) wireless communications.
- Competitive advantages
-
- Easily scalable and sustainable synthesis.
- Piezomagnetic property of ε -Fe2O3 makes it possible to obtain magnetized parts by sintering the material under uniaxial pressure.
- Magnetized nanoparticles can be used in planar microstrips circulators.
