“…The MnCoSi-based alloys are termed as the most promising candidate owing to their lower cost and higher magnetostrictive coefficient [ 10 ]. In addition, MnCoSi-based alloys as a new type of magneto-response material have attracted increasing attention, due to their rich magnetic structure (cycloid type and helical type antiferromagnetic structure, linear ferromagnetic structure) [ 11 , 12 , 13 ] and rich functional behaviors (magnetocaloric effect [ 14 , 15 ], magnetostrictive effect [ 8 , 9 ], anomalous thermal expansion effect [ 13 , 16 ] and magnetoresistance effect [ 17 , 18 ]).…”
