Quantifying Magnetic Anisotropy of Ferroelectric Fe(II) Square‐Pyramidal Systems Using Torque Magnetometry

Advanced Science, EarlyView.
Five‐coordinate, square‐pyramidal Fe(II) complexes adopting polar, non‐centrosymmetric crystal structures exhibit exceptionally large easy‐axis magnetic anisotropy. Ligand‐driven distortions critically control the anisotropy, and the dielectric, Polarization vs Elecric field and piezo response studies confirm intrinsic polarization, positioning these ...

Interpretable Machine Learning Framework for Nb─Si Based Alloy Design with Enhanced Fracture Toughness

Advanced Science, EarlyView.
An interpretable machine learning framework integrating SHAP and PDP analysis identifies critical design descriptors from 139 physicochemical features for Nb─Si alloys. The framework achieves <7% prediction error and guides the discovery of Nb38.5Ti38.5Si3Zr18V2 alloy with 22.791 MPa·m1/2 fracture toughness, breaking the 20 MPa·m1/2 barrier.

Piezoelectric Property of Otoliths

Science, 1967
Otoliths of two species of bony fishes have been found to be piezoelectric. Hence, in theory, they constitute a mechanism for depth perception or frequency analysis of sound waves, or both.

Fabrication of Piezoelectric-Rubber of Large Piezoelectric Property

MRS Proceedings, 2014
ABSTRACTIn the previous investigation, piezoelectric properties of the ‘Aligned-type’ in which the piezoelectric-ceramic particles are formed in linear aggregates in the rubber, remarkable piezoelectric properties were confirmed. In this investigation, to further enhance the piezoelectric properties of the Aligned-type, the influence of the matrix ...

Piezoelectric and Acoustic Properties of Piezoelectric Flexible Composites

Japanese Journal of Applied Physics, 1987
Piezoelectric and acoustic properties of piezoelectric flexible composites or Piezo-Rubbers which have been developed at NTK-NGK are reported. The frequency dependences and hydrostatic pressure dependences of underwater receiving sensitivities of hydrophone using the Piezo-Rubber are discussed in terms of the properties of Piezo-Rubber materials ...

Piezoelectric Properties of Triglycine Sulphate

Journal of the Physical Society of Japan, 1961
Since triglycine sulphate crystal is centrosymmetric above the Curie point, the piezoelectricity in the ferroelectric phase is expected to be an “induced” one as in the case of barium titanate, distinct from an “intrinsic” piezoelectricity of rochelle salt.
