铁磁性

This paper introduced the preparation of stable iron-nitride magnetic fluid by vapor-liquid chemical reaction between iron carbonyl and ammonia.

通过氨气和五羰基铁之间的气-液化学反应，制备出了稳定的氮化铁磁性液体。

When the temperature is less than 15 K, the PBTCA-Nd~(3+) complex is a ferromagnet, otherwise, it is a diamagnet. Both PPHBT-Nd~(3+) and PPHPHN-Nd~(3+) exhibit the characteristic of soft-magnetic materials at low temperature, the Curie-Weiss temperature are 80 K and 150 K, respectively.

实验结果表明，含咔唑聚合物的稀土配合物PBTCA-Nd~(3+)表现出特殊的软铁磁性，具有一个磁转变温度15 K，低于此温度时配合物是个铁磁体，反之，为抗磁体。

We try to synthesize the Co doped TiO2 dilute magnetic semiconductor structure via thermal treatments under vacuum environment, and study its magnetic property. The results reveal that during thermal treatments in a vacuum environment, the Co grains may form the oxide phase structure, and lose their magnetic properties.

研究结果发现在真空高温退火过程中，虽然钴粒子会均匀扩散至非晶的二氧化钛薄膜，其铁磁性的行为却因此消失，由实验结果推断在高温回火过程中，钴可能形成反铁磁的氧化物的结构。

At this year's March meeting of the American Physical Society, the group reported that this gossamer substance is ferromagnetic, the only type of pure carbon that has that property.

在今年3月举行的美国物理学年会中，该研究群发表了这种薄纱状的物质能拥有像铁一样的铁磁性，这可是纯碳物质中唯一具有这种特性的例子。

Iron is ferromagnetic at ordinary temperatures and is the only metal that can be tempered.

铁在常温下具有铁磁性，也是唯一可被回火的金属。

Microstructure and phase transformation behavior of Ni53Mn21Fe1Ga25 ferromagnetic shape memory alloy was investigated .

主要研究了少量掺铁对NiMnGa铁磁性形状记忆合金的相变行为和显微组织的影响。

No ferromagnetism was observed in stoichiometric HfO2 films, but we observed weak ferromagnetism in highly oxygen-deficient HfO2 films.

对于理想配比的HfO2薄膜，没有发现铁磁行为，但在高缺氧状态下的HfO2则观测到了弱的铁磁性。

Interpretation of the magnetic parameters suggests roughly constant proportions of haematite and magnetite with a predominance of ferrimagnetic grains in superparamagnetic and multidomain + pseudo singledomain grain sizes.

各监测点磁性参数的测试结果表明，高矫顽力的&赤铁矿&和低矫顽力的&磁铁矿&的含量之比大致变化不大，在这些气溶胶中，在超顺磁、多畴和伪单畴的矿物晶体颗粒中，以亚铁磁性矿物占优。

More importantly, ferrimagnetic iron sulphide is found in Unit A2 but absent in Unit A1, suggesting the control of marine environmental conditions on the magnetic mineral diagenesis.

铁磁性硫化物存在于A2段，但在A1段缺失，表明了海洋环境条件对磁性矿物成岩过程的控制。

Their formulas are presented as following:( 1 ) [Co2C6H2(COO44]n ( 2 ){[Co2(C2O4)C6H2(COO4(H2O)4] -4H2O-(NH2CH2COOH)}n ( 3 ){[Co(H2O)6][Co(H2O)4C6H2(COO4] . 4H2O}n These coordination polymers have been characterized by IR,UV-VIS-NIR spectroscopes. The variable temperature magnetic susceptibilities(1.5-300K)of complex (1) and (2) have been measured and studied. Complex (1) and (2) exhibit the anti-ferromagnetic property. The spin-transition phenomenon of complex (2) takes place at 17K.

经X-光衍射测定，确定了它们的结构，分子式如下：(1)[Co_2C_6H_2(COO_4_4]_n (2){[Co_2(C_2O_4)C_6H_2(COO_4(H_2O)_4]·4H_2O·(NH_2CH_2COOH)}_n (3){[Co(H_2O)_6][Co(H_2O)_4C_6H_2(COO_4]·4H_2O}_n 研究了上述三种配位聚合物的红外，紫外—可见—近红外光谱，测定了化合物(1)和(2)在1.5—300K温度范围内的变温磁矩，对它们的磁性研究表明，化合物(1)和(2)均呈反铁磁性，并且化合物(2)在17K发生了自旋转换现象。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
