Intrinsic effects of the boundary condition on the switching process of spin crossover solids (2009)

Nishino, Masamichi, Enachescu, Cristian, Miyashita, Seiji, Boukheddaden, Kamel, Varret, Francois

We investigated clustering dynamics of domains in switching processes between the low spin (LS) and high spin (HS) phases in thermal induced hysteresis loops of spin-crossover (SC) solids. In SC...

Simple Two-Dimensional Model for the Elastic Origin of Cooperativity among Spin States of Spin-Crossover Complexes (2007)

Nishino, Masamichi, Boukheddaden, Kamel, Konishi, Yusuké, Miyashita, Seiji

We study the origin of the cooperative nature of spin crossover (SC) between low spin (LS) and high spin (HS) states from the view point of elastic interactions among molecules. As the size of each...

Structure of Metastable States in Phase Transitions with High-Spin Low-Spin Degree of Freedom (2005)

Miyashita, Seiji, Konishi, Yusuke, Tokoro, Hiroko, Nishino, Masamichi, Boukheddaden, Kamel, Varret, Francios

Difference of degeneracy of the low-spin (LS) and high-spin (HS) states causes interesting entropy effects on spin-crossover phase transitions and charge transfer phase transitions in materials...

A Unified Theoretical Description of the Thermodynamical Properties of Spin Crossover with Magnetic Interactions (2005)

Boukheddaden, Kamel, Nishino, Masamichi, Miyashita, Seiji, Varret, Francois

After the discovery of the phenomena of light-induced excited spin state trapping (LIESST), the functional properties of metal complexes have been studied intensively. Among them, cooperative...

Dynamical Aspects of Photoinduced Magnetism and Spin-Crossover phenomena in Prussian Blue Analogs (2005)

Nishino, Masamichi, Boukheddaden, Kamel, Miyashita, Seiji, Varret, Francois

We present dynamical properties of spin crossover compounds with photomagnetization, proposing a new model in which the spin-crossover phenomena and magnetic ordering are incorporated in a unified...
