除某些富铁氧化物与硫化物之外,大多数含铁矿物都是顺磁性的。近年来曾有报道指出,若干富铁的硅酸盐矿物在低温下出现磁性有序现象。继莱河矿的研究之后,本文报道含铁矿物在低温下磁性有序的又一实例——硼镁铁矿与合成硼铁矿。
With the exception of some iron-rich oxides and sulfides, most iron-bearing minerals are paramagnetic. It has been reported in recent years that some iron-rich silicate minerals appear in a magnetic order at low temperatures. Following the study of Laihe Mine, this paper reports another example of magnetically ordered iron-bearing minerals at low temperatures - boron-magnesium-iron ore and synthetic boron-iron ore.
