Deformation of single-crystal Mn3Sn

Magnetic anisotropy of single-crystalline Mn3Sn in triangular and helix-phase states

“…1(a) and 1(b), Mn 3 Sn has the hexagonal Ni 3 Sn-type (D0 19 ) of structure with space group P6 3 / mmc stacking sequence ABABAB. 8 Mn 3 Sn is an antiferromagnet (AFM) with a N eel temperature (T N ) of 420 K. The magnetic configuration is triangular at 300 K, as demonstrated by powder neutron diffraction. Another magnetic transition occurs at T 1 ¼ 270 K. 9 Nagamiya et al 10,11 have proposed two models for the spin orders: below T 1 , the spin configuration is spiral, and above T 1 , it is triangular.…”

Plastic deformation behavior of Ni3(Ti0.7Nb0.3) single crystals with D019 structure

“…Taking the observed slip plane of f2111g into consideration, the Burgers vector of dislocations should be parallel to < 2116 >. The f2111g < 2116 > slip system was previously reported to be operative in some other D0 19 -structured compounds [18][19][20][21]. Since only the dislocations caused by the pyramidal slip contain the c-component in their Burgers vector, they may play an important role to yield the ductility of this compound in its polycrystalline form.…”

Out-of-plane weak ferromagnetism at room temperature in lattice-distortion non-collinear antiferromagnet of single-crystal Mn3Sn

“…4(b)]. The significant enhancement of the magnetic properties may stem from the slight crystal slip [29] and the distortion of the crystal structure, where the compression deformation parallel to [11 20] in DS2 stretches the lattice constant c and reduces a. In short, whether the value of c/a increases or decreases, the spin structure of OWFM can be deduced to enhance the magnetic properties of the sample.…”
