Magnetization processes and transitions between two antiferromagnetic spin configurations in single-crystalline MnSn 2

Electronic and thermal transport properties of the metallic antiferromagnet MnSn2

“…We speculate that all the curves measured below T N1 experience a jump at certain high fields, which is not given here due to the limitation of experimental conditions. 20 The magnetization curve along the perpendicular [110] axis changes with temperature in a similar manner, and the corresponding field values slightly increase, which can be attributed to the axial anisotropy in MnSn 2 .…”

“…The H C derived from the MR is consistent with that from M ( H ), as it is exactly the manifestation of the same AFM I phase in its magnetism and transport behavior. 20,24 Then, the MR becomes negative in the whole field range, whereas the absolute value of the MR decreases monotonically with increasing temperature. It could be related to the suppression of magnetic scattering and the increasing ρ ( T , 0) due to enhanced electron–phonon scattering.…”

“…MnSn 2 is antiferromagnetic with a Néel temperature around T N2 ≈ 320 K (the paramagnetic state to the AFM I state), above an abrupt magnetic-ordering transition at T N1 ≈ 74 K [the AFM I state (+ − + −) to the AFM II state (+ + − −)]. 20 The larger values and a relatively small anomaly around T N2 for the [110] direction are consistent with the conclusion of the neutron-intensity measurements, which indicated that the propagation vector directed along [110], as well as the AF spin axis. 23…”

“…18 The Mn atoms form chains parallel to the c axis, and each Mn atom is surrounded by eight Sn atoms in a square antiprism. 4,17,19,20 It has been demonstrated that MnSn 2 is antiferromagnetic with a Néel temperature around 325 K. 20 However, previous research on MnSn 2 mainly focused on magnetism or theoretical calculations, 17,20 and there is still no detailed experimental studies of other physical properties reported as far as we know.…”

In-Magnetic-Field Heat Treatment Effects on Phase Growth of Mn–Bi–Sn Composite

“…31) Recently, IFHT for non-FM Mn-Sn systems was conducted at 553 K, which is higher than the melting point (505 K) of Sn, and magnetically oriented textures of blockor bar-like shaped MnSn 2 on the Sn matrix were reported. 32) Non-FM Mn-Sn system has three intermetallic phases: 33,34) FM Mn 3 Sn 2 with T C = 262 K, 35) antiferromagnetic (AFM) Mn 3 Sn with Néel temperature of T N = 420 K 36) and AFM MnSn 2 with T N = 325 K. 37) However, there is no detailed reported on MFE on the phase growth of FM-Mn 3 Sn 2 , AFM-Mn 3 Sn and AFM-MnSn 2 by IFHT.…”
