Incommensurate modulation with $Q = 0$ A-type Antiferromagnetic Order in CeRh $_{2}$ As $_{2}$ revealed by NQR studies

Shiki Ogata, Shunsaku Kitagawa, Kenji Ishida +4

We performed $^{75}$ As nuclear quadrupole resonance (NQR) and nuclear magnetic resonance (NMR) measurements on a higher-quality single-crystalline CeRh $_{2}$ As $_{2}$ , a heavy-fermion s…

Conventional $s$ -wave Superconductivity in LaRh $_{2}$ As $_{2}$ ; the Analog without the 4 $f$ Electrons of CeRh $_{2}$ As $_{2}$

Shiki Ogata, Shunsaku Kitagawa, Kenji Ishida +4

Superconductor LaRh $_{2}$ As $_{2}$ has the same crystal structures as CeRh $_{2}$ As $_{2}$ , which exhibits superconducting (SC) multiphase in the $c$ -axis magnetic field. Although the SC tran…

Multilayer Crystal Field states from locally broken centrosymmetry

Owen Moulding, Makoto Shimizu, Amit Pawbake +9

Local charge, spin, or orbital degrees of freedom with intersite interactions are oftentimes sufficient to construct most quantum orders. This is conventionally true for f-electron…

The phase diagram of CeRh $_{2}$ As $_{2}$ for out-of-plane magnetic field

P. Khanenko, J. F. Landaeta, S. Ruet +10

The heavy-fermion superconductor CeRh $_{2}$ As $_{2}$ ( $T_{c} = 0.35 K$ ) shows two superconducting (SC) phases, SC1 and SC2, when a magnetic field is applied para…

Odd-parity superconductivity underpinned by antiferromagnetism in heavy fermion metal YbRh $_{2}$ Si $_{2}$

Lev V. Levitin, Jan Knapp, Petra KnappovÃ¡ +13

Topological superconductors are essential elements of the periodic table of topological quantum matter. However, the relevant odd-parity spin-triplet superconductors are rare. We r…
