报道了Pd的顺磁磁化率CHI的电荷诱导可逆变化。通过纳米晶-电解液复合材料进行原位充电。考虑到表面电荷对载流子密度的影响和电荷诱导压力对纳米晶的影响，分析了CHI的电荷诱导变化。目前的研究可能为实现可转换铁磁性开辟道路。(C)2006年美国物理研究所。
A charge-induced reversible variation of the paramagnetic susceptibility chi of Pd is reported. In situ charging was performed by means of a nanocrystallite-electrolyte composite. The charge-induced variation of chi is analyzed taking into account the modification of the charge carrier density by surface charging and the effect of charge-induced pressure on the nanocrystallites. The present studies may open up the way to switchable ferromagnetism. (c) 2006 American Institute of Physics.
