| 1 | Ni_2MnGa铁磁形状记忆材料显示文摘铁磁形状记忆合金 (FSMA)是在一定温度范围马氏体相稳定同时又具铁磁性的一类特殊的形状记忆合金。Ni2MnGa铁磁形状记忆合金近年来成为呈现磁场驱动大应变的新型驱动材料 ,这些应变来自磁场诱发马氏体孪晶的重排 ,而不是磁场对奥氏体至马氏体相变的作用。孪晶变体的重排在宏观上呈现为正或切应变 ,一非化学计量比Ni2 MnGa单晶于室温加 0 .4T磁场能产生6 %的应变 ,Ni Mn Ga单晶在高至 15 0Hz的交变磁场仍可得到 2 .5 %的应变。本文阐述了与这种磁控形状记忆效应相关的孪晶界迁动的磁学和晶体学理论。马氏体相的大磁晶各向异性能使磁化沿c轴方向有利 ,穿过孪晶界c轴刚好转动 90度 ,同时 ,这个孪晶界也构成了约 90度的畴界。在各向异性的情况下 ,孪晶界的迁动仅有相邻孪晶变体的Zeeman能差驱动 ,μ0 ΔMis·Hi。磁场和外应力对应变的影响通过对一简单的自由能表达式取极小值来表示 ,自由能表达式包括Zeeman能、磁晶各向异性能和外应力以及在某些情况下需考虑的内部弹性能 ,模型的所有参数可通过应力 应变曲线和磁化曲线测量得到。铁磁形状记忆合金的磁场诱发应变可类比传统热弹性形状记忆效应 ,与更为人们所熟知的磁致伸缩现象不同。 | 金学军 彭志明 R.C.O’Handley S.M.Allen 徐祖耀 | 2003 | 世界科技研究与发展2003，25，1： | 3 |
| 2 | Iron in the NEEM ice core relative to Asian loess records over the last glacial–interglacial cycle显示文摘Mineral dust can indirectly affect the climate by supplying bioavailable iron(Fe)to the ocean.Here,we present the records of dissolved Fe(DFe)and total Fe(TDFe)in North Greenland Eemian Ice Drilling(NEEM)ice core over the past 110 kyr BP.The Fe records are significantly negatively correlated with the carbon-dioxide(CO_(2))concentrations during cold periods.The results suggest that the changes in Fe fluxes over the past 110 kyr BP in the NEEM ice core are consistent with those in Chinese loess records because the mineral-dust distribution is controlled by the East Asian deserts.Furthermore,the variations in the dust input on a global scale are most likely driven by changes in solar radiation during the last glacial–interglacial cycle in response to Earth’s orbital cycles.In the last glacial–interglacial cycle,the DFe/TDFe ratios were higher during the warm periods(following the post-Industrial Revolution and during the Holocene and last interglacial period)than during the main cold period(i.e.the last glacial maximum(LGM)),indicating that the aeolian input of iron and the iron fertilization effect on the oceans have a non-linear relationship during different periods.Although the burning of biomass aerosols has released large amounts of DFe since the Industrial Revolution,no significant responses are observed in the DFe and TDFe variations during this period,indicating that severe anthropogenic contamination has no significant effect on the DFe(TDFe)release in the NEEM ice core. | Cunde Xiao Zhiheng Du Mike J Handley Paul A Mayewski Junji Cao Simon Schüpbach Tong Zhang Jean-Robert Petit Chuanjin Li Yeongcheol Han Yuefang Li Jiawen Ren | 2021 | National Science Review2021，8，7： | 2 |
