Tuning the Magnetic Ordering Temperature of Hexagonal Ferrites by Structural Distortion Control [PDF]

open access: yes, 2018
To tune the magnetic properties of hexagonal ferrites, a family of magnetoelectric multiferroic materials, by atomic-scale structural engineering, we studied the effect of structural distortion on the magnetic ordering temperature (TN).

Distortion of spheres and surfaces in space [PDF]

open access: yes, 2019
It is known that the surface of a cone over the unit disc with large height has smaller distortion than the standard embedding of the 2-sphere in $\mathbb R^3$.

Theory Based on Device Current Clipping to Explain and Predict Performance Including Distortion of Power Amplifiers for Wireless Communication Systems [PDF]

open access: yes, 2008
Power amplifiers are critical components in wireless communication systems that need to have high efficiency, in order to conserve battery life and minimise heat generation, and at the same time low distortion, in order to prevent increase of bit ...
