“…This compound is a ferromagnet with the Curie temperature around 400 K and with the magnetic moment of 3 B per molecule, which is mainly carried by the Mn atoms [3][4][5][6]. When we see this crystal along c-axis, (Mn + P) atoms form ferromagnetic layers.…”

“…The Mn-based compounds, MnMX (M = Ru, Rh, Pd and X = P, As), crystallize in the hexagonal Fe 2 P-type, each featuring tetragonal (with 4d atoms) and square-base pyramidal (with 3d atoms) metal sites with pseudo twodimensionality along the c-axis. 32 Many essential features of solid-state materials have been discovered, including phase transitions, which are caused by changes in either pressure or temperature or both. As an example, the Fe 2 P compound undergoes a magnetic phase transition above 5 kbar.…”

“…The reported values of dT C /dP for MnRhP and MnRhAs are +11.6 and +7.1 K/GPa, respectively. 39,40 MnRhP has been investigated at ambient and high pressures and shown to exhibit an FM behavior with a T C of 400 K. 32 The magnetic moment of MnRhP at 4.2 K was found to be 3.0 μ B per formula unit. The spontaneous magnetization of MnRhP at a low temperature (4.2 K) was investigated up to 0.76 GPa, and it was observed that the T C of MnRhP increases linearly with pressure, and the value of dT C /dP is +1.2−1.5 K/kbar.…”

Prediction of Ground State Structures and Robust Weyl Fermionic States in MnRhP

Topological metals are a new class of materials that feature Fermionic quasiparticles with the presence of non-trivial band crossings near the Fermi level. In this work, we focus on establishing crystal structure ground states and the corresponding topological properties of MnRhP. Under ambient pressure and low temperatures, we find that an orthorhombic oP12 polymorph is favored over the known hexagonal hP9 phase. Pressures above 15 GPa stabilize tetragonal (tP6′), hexagonal (hP9′), and orthorhombic (oP12′) phases with inverted population of metal sites. While oP12′ has the lowest enthalpy, we show that hP9′ is more consistent with the previous X-ray diffraction data collected at 60 GPa. Our analysis of hP9 and oP12 topological properties reveals the existence of nodal lines around the Γ-point that are gapped out when spin–orbit coupling effects are included and transform into Weyl nodes with opposite chirality near the Fermi level. The calculated large values of the anomalous Hall conductivity in hP9, oP12, and tP6′ and the Z 2 topological invariant in the non-magnetic hP9′ can be used to verify the predicted non-trivial robust topological features of MnRhP under ambient and high pressures.

“…Equiatomic intermetallic T T X compounds (T : electronpoor transition metal, T : electron-rich transition metal, X : P, As, and Si) have been widely investigated in the least 50 years with respect to their interesting structural [1][2][3][4][5][6][7][8][9][10][11][12][13] and magnetic [14][15][16][17][18][19][20][21][22][23][24][25][26] properties. Related to the size and the electron count of the transition metal, these compounds either exist in the orthorhombic TiNiSi-type structure [1] or the hexagonal ZrNiAl-type structure [3].…”

Investigating the normal state and superconducting state properties of orthorhombic and hexagonal ZrRuP: A first-principles study

et al. 2019

We have executed ab initio pseudopotential calculations on the structural, electronic, elastic, mechanical, vibrational, and electron-phonon interaction properties of hexagonal ZrRuP (h-ZrRuP) and orthorhombic ZrRuP (o-ZrRuP). The electronic states of both phases near the Fermi energy are found to be dominated by the d electrons of transition metal atoms, suggesting that they play a more active role in the generation of superconducting state for both phases of ZrRuP. A critical assessment of their elastic and mechanical properties reveals that the lattice of h-ZrRuP is softer than that of o-ZrRuP. A comparison of phonon dispersion curves for both phases indicates that the lower transverse acoustic branch of h-ZrRuP is much softer than that of o-ZrRuP. The soft character of this phonon branch gives rise to strong electron-phonon interaction in h-ZrRuP. Therefore the electron-phonon coupling parameter for h-ZrRuP equals to 1.25 which is considerably larger than the corresponding value of 0.57 for o-ZrRuP. As a consequence, phonon and electron-phonon interaction properties are crucial in making superconducting transition temperature much higher for h-ZrRuP than o-ZrRuP. At the end, the value of this temperature is found to be 12.49 K for h-ZrRuP and 3.89 K for o-ZrRuP which coincide with their experimental values of 12.93 and 3.82 K.
