本文报道了硼取代MnCoSi合金的结构、磁转变和磁致伸缩效应。通过用B替代2%的Si，室温临界场急剧降低到0.8 T，三临界点的温度被调谐到270 K左右。作为这些改进的结果，大的可逆磁致伸缩下降低驱动场实现在室温下织构MnCoSi 0.98B 0.02合金。(C)2016 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
In this paper, we report on the structure, magnetic transition and the magnetostrictive effect in B-substituted MnCoSi alloys. By replacing 2% Si with B, the room-temperature critical field is sharply reduced to 0.8 T and. the temperature of tricritical point is tuned down to be around 270 K. As the results of these improvements, large reversible magnetostriction under reduced driving field is achieved at room temperature in textured MnCoSi0.98B0.02 alloy. (C) 2016 Acta Materialia Inc.
