Higher harmonics in planar Hall effect induced by cluster magnetic multipoles [PDF]

open access: yesNature Communications, 2022
The lack of net magnetization in antiferromagnets makes them technologically promising, but it also makes detecting the spin orders challenging. Here, using electrical transport measurement, Song et al show how the planar Hall effect can detect different

Unlocking higher harmonics in atomic force microscopy with gentle interactions [PDF]

open access: yesBeilstein Journal of Nanotechnology, 2014
In dynamic atomic force microscopy, nanoscale properties are encoded in the higher harmonics. Nevertheless, when gentle interactions and minimal invasiveness are required, these harmonics are typically undetectable.

Experimental identification of cracked rotor system parameters from the forward and backward whirl responses [PDF]

open access: yesArchive of Mechanical Engineering, 2019
In the present work, an experimental investigation of a transverse fatigue crack has been carried out. A mathematical modelling of cracked rotor system along with the measured vibration is used to find crack parameters that not only detect the fault but ...

Application of the Sinusoidal Voltage for Detection of the Resonance in Inductive Voltage Transformers

open access: yesEnergies, 2021
In the case of the inductive voltage transformer (VT), the resonance phenomenon may be the main reason for its poor transformation accuracy of the non-sinusoidal voltage.
