Abnormal low-field M-type magnetoresistance in hexagonal noncollinear ferromagnetic MnFeGe alloy
文献摘要:
The new magnetic degree of freedom provided by the noncollinear structure plays an important role in the development of spintronic devices.In this work,we con-ducted a systematic study on the magnetic and electrical transport properties of the hexagonal noncollinear ferro-magnetic MnFeGe alloy.Abnormal Hall effect and mod-erate magnetoresistance(MR)were observed below the Curie temperature(~200 K)of MnFeGe,in both bulk and thin-film forms.Notably,the perpendicular MR in all samples firstly grows,then quasi-linearly descends with magnetic field increasing,making an irregular M-type MR in the low-field region.It is speculated that the abnormal MR is related to the magnetic domain change,and com-bined with micromagnetic simulations,the labyrinth domain and sparse bubble formation are verified to exist in MnFeGe.Our work offers an understanding of the low-field-positive MR in a ferromagnet,as well as raises the possibility of magnetic bubble formation in this non-collinear system.
