2014 Journal of the Physical Society of Japan  
Ba_2CoSi_2O_6Cl_2 exhibits a stepwise magnetization process with a plateau at half of the saturation magnetization, irrespective of the field direction, although all the Co^2+ sites are equivalent.  ...  This indicates that spin triplets are localized owing to the almost perfect frustration of interdimer exchange interactions.  ...  If the interdimer exchange interactions are confined between nearest-neighbor dimers and are perfectly frustrated, a stepwise magnetization process with the M s /2 plateau occurs, as observed in the present  ...

Understanding Adsorption-Desorption Dynamics of BMP-2 on Hydroxyapatite (001) Surface

Xiuli Dong, Qi Wang, Tao Wu, Haihua Pan
2007 Biophysical Journal  
If there were more than one set of adsorption groups for a certain orientation of protein, the adsorption-desorption process would likely be stepwise.  ...  The results suggest that there are three types of functional groups through which BMP-2 can interact with HAP crystallite, and they are -OH, -NH 2 , and -COO À .  ...  This work was financially supported by the National Natural Science Foundation of China (grant No. 60533050 and grant No. 20503025).  ...
