Superconducting pairing symmetry in MoTe$_{2}$

Autor: Piva, M. M., Kutelak, L. O., Borth, R., Liu, Y., Petrovic, C., Reis, R. D. dos, Nicklas, M.

Publikováno v: Phys. Rev. Materials 7 L111801 (2023)

Topological superconductors have long been sought for their potential use in quantum computing. The type-II Weyl semimetal MoTe$_{2}$ is an obvious candidate, exhibiting a superconducting state below 500 mK at ambient pressure, but the question remai

Heat-capacity measurements under uniaxial pressure using a piezo-driven device

Autor: Li, Y. -S., Borth, R., Hicks, C. W., Mackenzie, A. P., Nicklas, M.

Publikováno v: Rev. Sci. Instrum. 91, 103903 (2020)

We report the development of a technique to measure heat capacity at large uniaxial pressure using a piezoelectric-driven device generating compressive and tensile strain in the sample. Our setup is optimized for temperatures ranging from 8 K down to

CeIr$_{3}$Ge$_{7}$: a local moment antiferromagnetic metal with extremely low ordering temperature

Autor: Rai, Binod K., Banda, Jacintha, Stavinoha, Macy, Borth, R., Jang, D. -J., Benavides, Katherine A., Sokolov, D. A., Chan, Julia Y., Nicklas, M., Brando, Manuel, Huang, C. -L., Morosan, E.

Publikováno v: Phys. Rev. B 98, 195119 (2018)

CeIr$_3$Ge$_7$ is an antiferromagnetic metal with a remarkably low ordering temperature $T_{\rm N}$ = 0.63 K, while most Ce-based magnets order between 2 and 15 K. Thermodynamic and transport properties as a function of magnetic field or pressure do

Charge-Doping driven Evolution of Magnetism and non-Fermi-Liquid Behavior in the Filled Skutterudite CePt4Ge12-xSbx

Autor: Nicklas, M., Kirchner, S., Borth, R., Gumeniuk, R., Schnelle, W., Rosner, H., Borrmann, H., Leithe-Jasper, A., Grin, Yu., Steglich, F.

Publikováno v: Phys. Rev. Lett. 109, 236405 (2012)

The filled-skutterudite compound CePt4Ge12 is situated close to the border between intermediate-valence of Ce and heavy-fermion behavior. Substitution of Ge by Sb drives the system into a strongly correlated and ultimately upon further increasing the

Magnetism and unconventional superconductivity in Ce$_n$M$_m$In$_{3n+2m}$ heavy-fermion crystals

Autor: Thompson, J. D., Nicklas, M., Bianchi, A., Movshovich, R., Llobet, A., Bao, W., Malinowski, A., Hundley, M. F., Moreno, N. O., Pagliuso, P. G., Sarrao, J. L., Nakatsuji, S., Fisk, Z., Borth, R., Lengyel, E., Oeschler, N., Sparn, G., Steglich, F.

Publikováno v: Physica B 329-333, 446 (2003)

We review magnetic, superconducting and non-Fermi-liquid properties of the structurally layered heavy-fermion compounds Ce$_n$M$_m$In$_{3n+2m}$ (M=Co, Rh, Ir). These properties suggest d-wave superconductivity and proximity to an antiferromagetic qua

Response of the Heavy-Fermion Superconductor CeCoIn$_5$ to Pressure: Roles of Dimensionality and Proximity to a Quantum-Critical Point

Autor: Nicklas, M., Borth, R., Lengyel, E., Pagliuso, P. G., Sarrao, J. L., Sidorov, V. A., Sparn, G., Steglich, F., Thompson, J. D.

Publikováno v: J. Phys.: Condens. Matter 13 No 44 (5 November 2001) L905-L912

We report measurements of the pressure-dependent superconducting transition temperature $T_c$ and electrical resistivity of the heavy-fermion compound CeCoIn$_5$. Pressure moves CeCoIn$_5$ away from its proximity to a quantum-critical point at atmosp
