Analysis of Self-assembly Lattice Structures Composed of Cubic Hematite Particles
KAGAKU KOGAKU RONBUNSHU, 2010 一辺の長さが約0.9 μmのキューブ状ヘマタイト粒子からなる，格子構造を有する自己集合膜の構造解析を行った．キューブ状粒子はFeCl3水溶液を373 Kで8 d間エージングして合成した．粒子の直接光学顕微鏡観察から，デジタル画像解析法により動径分布関数を決定した．弱い磁場と粒子間の磁気的相互作用が格子構造に及ぼす影響を明らかにするため，キューブ状ヘマタイト粒子の2次元モンテカルロ・シミュレーションも行った．非常に弱い地磁気の場合，粒子の沈降過程を通して鎖状および正方格子構造がガラス平板上に形成した．シミュレーションの結果から，正方格子構造は粒子の磁気モーメントのジグザグな配向によって安定化していることが明らかになった．比較的強い磁場の場合 ...

Application of the Brownian dynamics method to magnetic cube-like particle suspensions
Nihon Kikai Gakkai ronbunshu, 2019 In the present study, we propose a new repulsive layer model in order to establish Brownian dynamics simulations for cube-like particles, although various repulsive layer models have been proposed by other researchers.
