R. H. Chen,R.Y. Chang,S.C. Shern +2 more
TL;DR: In this paper, a single crystal of K 3 H(SeO 4 ) 2 has been observed to transform from monoclinic to trigonal in the high-temperature phase at around 110°C.
Journal ArticleDOI
Impedance spectroscopy and dielectric analysis in KH2PO4 single crystal
TL;DR: In this article, the activation energy of migration is 1.02 eV in the temperature range between 150 and 179 eV and 2.94 eV at temperatures above 186 eV.
Journal ArticleDOI
Studies on the dielectric properties and structural phase transition of K2SO4 crystal
TL;DR: In this article, the temperature and frequency dependence of electrical conductivity, dielectric constant, and electrical modulus were determined, and the activation energies and characteristic relaxation times were calculated.
Journal ArticleDOI
Response and enhancement of surface magneto-optic Kerr effect for Co–Pt(111) ultrathin films and surface alloy
TL;DR: In this paper, the magnetic anisotropy of a flat and sputtered Pt(111) surface by a surface magneto-optic Kerr effect was comparatively studied, and a large enhancement was observed after one atomic layer of Co adatoms was annealed at 710 K. The mechanism of the enhancement was discussed.
