Semiquantitative theory for high-field low-temperature properties of a distorted diamond spin chain [PDF]

open access: yesCondensed Matter Physics, 2012
We consider the antiferromagnetic Heisenberg model on a distorted diamond chain and use the localized-magnon picture adapted to a distorted geometry to discuss some of its high-field low-temperature properties.

Ultra-precision grinding of 4H-SiC wafer by PAV/PF composite sol-gel diamond wheel

open access: yesAdvances in Mechanical Engineering, 2021
To eliminate the deep scratches on the 4H-SiC wafer surface in the grinding process, a PVA/PF composite sol-gel diamond wheel was proposed. Diamond and fillers are sheared and dispersed in the polyvinyl alcohol-phenolic resin composite sol glue ...

Spin nematic liquid of the S = 1/2 distorted diamond spin chain in magnetic field

open access: yesAIP Advances, 2023
The magnetization process of the S = 1/2 distorted diamond spin chain with anisotropic ferromagnetic interaction is investigated using numerical diagonalization of finite-size clusters. It is found that the spin nematic and SDW Tomonaga-Luttinger liquids
