Resistivity and spontaneous anisotropy of resistivity in amorphous Fe_xSi_1-x films

Analysis of the magnetoresistance contributions in a nanocrystallized Cr-doped FINEMET alloy

“…Such a behaviour has already been reported previously for the nanocrystallized state of a Fe 78 B 13 Si 9 [13], a Fe 72 V 3 Cu 1 Si 16 B 8 [16] and two FINEMET type alloys [14,15]. On the other hand, in the amorphous state of Fe-based metal-metalloid alloys, all reported magnetoresistance data [8][9][10][11][12][13][14][15][16]26] indicate a positive AMR and the same was found even for sputtered amorphous Fe-Si thin films [27,28]. Therefore, since in all the above listed nanocrystallized alloys as well as in our one, the FM grains consist of a Fe-Si alloy with the D0 3 structure, evidently these grains can be made responsible for the negative AMR effect observed in these nanocrystallized alloys.…”

“…Therefore, since in all the above listed nanocrystallized alloys as well as in our one, the FM grains consist of a Fe-Si alloy with the D0 3 structure, evidently these grains can be made responsible for the negative AMR effect observed in these nanocrystallized alloys. This has already been suggested [14,15] on the basis of old MR data on bulk Fe-Si alloys [29] and are supported also by MR results obtained more recently on crystallizing sputtered amorphous Fe-Si thin films [28]. All this also constituted a motivation for us to perform a more detailed study on the MR behaviour of rapidly quenched Fe-Si ribbons, and the results are presented in Section 3.2.…”

Experimental Study of the Magnetic Contribution to the Resistivity in Iron Based Amorphous Alloys

“…SAR effect is linear with M 2 (T). This expected behaviour is also very clear in a-Fe^ Sii-* [12] with 0.55 < a; < 0.75.…”

Spectroscopic and Optoelectronic Properties of Hydrogenated Amorphous Silicon-Chalcogen Alloys

“…There has been an intensive research work during the past two decades to search for stable and low defect density material for use in tandem with a-Si:H-based photovoltaic devices [1][2][3][4][5]. a-Si:H-based alloys proved to be attractive materials with a wide range of applications including solar cells, photoreceptors, displays, and imaging devices [6][7][8][9].…”
