“…GdRh 3 B is of perovskite-type cubic structure: space group Pm3m; Z = 1. The lattice parameter a is 4.183(1)Å [24]. The respective isomer shift is 0.11(1) mm s −1 and 0.08(1) mm s −1 and this shows the decrease in the isomer shift as the decrease in the boron content.…”

“…YRh 3 B sample was prepared via the arc-melting method in a titanium-gettered argon atmosphere before [49]. In this work, the lattice constants of YRh 3 B were totally relaxed via first-principles calculation, and the obtained values were a = b = c = 4.1996 Å, which are in good agreement with the experimental values [49], namely a = b = c = 4.22 Å. The optimized crystal structure of YRh 3 B at its equilibrium lattice constants is shown in Fig.…”

Experimentally synthesized perovskite-type YRh3B with a P m 3m type structure was proposed as a novel topological material (TM) via first-principles calculations and the low-energy k • p effective Hamiltonian, which has a quadratic contact triple point (QCTP) at point Γ and six pairs of open nodal lines (NLs) of the hybrid type. Clear surface states observed in the surface spectrum confirmed the topological states. When spin-orbit coupling was considered, the QCTP at Γ transferred to the quadratic-type Dirac nodal point (NP). Under 1% tetragonal strained lattice constants, YRh3B hosted richer topological states, including a quadratic-type two-fold degenerate NP, six pairs of open NLs of the hybrid type, and two closed NLs of type I and hybrid type. Moreover, it was proved that the NLs of YRh3B at its strained lattice constants contain all types of band-crossing points (BCPs) (i.e., type I, type II, and critical type). Such rich types of NP and NL states in one compound make it potentially applicable for multifunctional electronic devices as well as an appropriate platform to study entanglement among topological states.

“…Intermetallic anti-perovskites closely related to MgCNi 3 are therefore subjected to investigations for both the search for new superconductors and the pursuit of a better understanding of the interplay between superconductivity and magnetism. Boron-containing anti-perovskites have been the subject of many experimental and theoretical research work in the last years [1,3,[12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. Holleck [27] synthesized some cubic antiperovskite borides Sc-based ABSc 3 , where A = Sn, Pb, In and Tl.…”
