“…The a and c constants in the Mn rich tetragonal phase also present a good accordance to the literature [25,26], decreasing with increasing Fe content. Si substitution on this area also increases both a and c, coming from an a of 9.179Å and a c of 4.568Å for Mn 3 P to 9.183Å and 4.607Å for Mn 3 Si 0.2 P 0.8 .…”

“…The lattice parameters of the orthorhombic phase were found to be slightly smaller than those reported by Goto et al [26], being a = 8.9456Å, b = 8.0079Å and c = 4.3368Å for the Mn 1.5 Fe 1.5 P compound. Due to the secondary phases, belonging to both the Mn and the Fe rich tetragonal phase and the hexagonal phase, we were able to make a good fitting of our other orthorhombic samples.…”

“…The Mn 3−x Fe x P system maintains the same I4 tetragonal crystal structure for 0 < x < 1 [25,26] and again for 2.2 < x < 3 [24,26], approximately. In the gap between these two intervals an orthorhombic structure is reported [26].…”

Magnetic mineralogy of the Mercurian lithosphere

Mercury and Earth are the only inner solar system planets with active, internally generated dynamo magnetic fields. The MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) mission recently detected magnetic fields on Mercury that are consistent with lithospheric magnetization. We investigate the physical and chemical environment of Mercury's lithosphere, past and present, to establish the conditions under which magnetization may have been acquired and modified. Three factors are particularly crucial to the determination of crustal composition and iron mineralogy: redox conditions in the planet's crust and mantle, the iron content of the lithosphere, and, for any remanent magnetization, the temperature profile of the lithosphere and its evolution over time. We explore potential mechanisms for remanence acquisition and alteration on Mercury, whose surface environment is both hot and highly reducing. The long‐term thermal history of Mercury's crust plays an important role in the longevity of any remanent crustal magnetization, which may be subject to remagnetization through thermal, viscous, and shock mechanisms. This thermal and compositional framework is used both to constrain plausible candidate minerals that could carry magnetic remanence on Mercury and to evaluate their capacity to acquire and retain sufficient magnetization to be detectable from satellite orbit. We propose that iron metal and its alloys are likely to be the dominant contributors to induced and remanent magnetization in Mercury's lithosphere, with additional contributions from iron silicides, sulfides, and carbides.

Doping Control of Magnetic Anisotropy for Stable Antiskyrmion Formation in Schreibersite (Fe,Ni)₃P with S₄ symmetry

have been extensively studied in the last decade, both in the fields of fundamental science and applications to spintronics devices. [1,2] One of the well-known mechanisms of skyrmion formation is the competition between ferromagnetic exchange interaction and the Dzyaloshinskii-Moriya interaction (DMI) arising from the lack of inversion symmetry. Skyrmions with helical (Bloch type) and cycloidal (Néel type) spin configurations have been observed in non-centrosymmetric magnets with chiral (T or O class) and polar (C nv class) structures, respectively. [3][4][5][6][7][8][9] Recently, a new topological spin texture, the antiskyrmion, with opposite sign of N sk for the same polarity has attracted much attention. The antiskyrmion consists of both Bloch and Néel walls with the opposite helicities along two orthogonal axes, and its formation is attributed to the anisotropic DMI present in non-centrosymmetric tetragonal crystals belonging to the D 2d or S 4 symmetry group both containing fourfold rotoinversion (4). [10,11] In real materials, antiskyrmions were first found in Heusler compounds with D 2d symmetry, Mn 1.4 PtSn and Mn 1.4 Pt 0.9 Pd 0.1 Sn. [12,13] More recently, the formation of antiskyrmions was also found in Fe 1.9 Ni 0.9 Pd 0.2 P [Pd-doped (Fe,Ni) 3 P] with S 4 symmetry [14] and Fe/Gd-based multilayers. [15] Lorentz transmission electron microscopy (LTEM) observation for thin plates of these Magnetic skyrmions, vortex-like topological spin textures, have attracted much interest in a wide range of research fields from fundamental physics to spintronics applications. Recently, growing attention is also paid to antiskyrmions emerging with opposite topological charge in non-centrosymmetric magnets with D 2d or S 4 symmetry. In these magnets, complex interplay among anisotropic Dzyaloshinskii-Moriya interaction, uniaxial magnetic anisotropy, and magnetic dipolar interactions generates various magnetic textures. However, the precise role of these magnetic interactions in stabilizing antiskyrmions remains to be elucidated. In this work, the uniaxial magnetic anisotropy of schreibersite (Fe,Ni) 3 P with S 4 symmetry is controlled by doping and its impact on the stability of antiskyrmions is investigated. The authors' magnetometry study, supported by ferromagnetic resonance spectroscopy, shows that the variation of the Ni content and slight doping with 4d transition metals considerably change the magnetic anisotropy. In particular, doping with Pd induces easy-axis anisotropy, giving rise to formation of antiskyrmions, while a temperature-induced spin reorientation is observed in an Rh-doped compound. In combination with Lorentz transmission electron microscopy and micromagnetic simulations, the stability of antiskyrmion as functions of uniaxial anisotropy and demagnetization energy is quantitatively analyzed, and demonstrated that subtle balance between them is necessary to stabilize the antiskyrmions.
