Conventional superconductivity in single-crystalline BiPt

S. Sharma, M. Pula, Sajilesh K. P. +10

Binary Bi-Pd/Pt systems have attracted a lot of interest because of their topologically non-trivial nature along with superconductivity. We report the structural and superconductin…

Structure and magnetism of MnGe thin films grown with a nonmagnetic CrSi template

B. D. MacNeil, J. S. R. McCoombs, D. Kalliecharan +7

We report a method to grow B20 MnGe thin films using molecular-beam epitaxy, which employs an ultrathin CrSi template layer on Si(111). This layer is expected to be nonmagnetic, in…

Two-Peak Heat Capacity Accounts for $R ln (2)$ Entropy and Ground State Access in the Dipole-Octupole Pyrochlore Ce $_{2}$ Hf $_{2}$ O $_{7}$

E. M. Smith, A. Fitterman, R. SchÃ¤fer +18

Magnetic heat capacity measurements of a high-quality single crystal of the dipole-octupole pyrochlore Ce $_{2}$ Hf $_{2}$ O $_{7}$ down to a temperature of $T = 0.02$ K are reported. These s…

Ground-states of the Shastry-Sutherland Lattice Materials Gd $_{2}$ Be $_{2}$ GeO $_{7}$ and Dy $_{2}$ Be $_{2}$ GeO $_{7}$

M. Pula, S. Sharma, J. Gautreau +3

The recent realization that the rare-earth melilites RE $_{2}$ Be $_{2}$ GeO $_{7}$ host the Shastry-Sutherland lattice within planes of RE $^{3 +}$ ions has sparked a number of studies. This f…

Fractionalized Magnetization Plateaus in the Shastry-Sutherland Lattice Material Er $_{2}$ Be $_{2}$ GeO $_{7}$

M. Pula, S. Sharma, J. Gautreau +6

The experimental study of magnetism on the Shastry-Sutherland lattice has been ongoing for more than two decades, following the discovery of the first Shastry-Sutherland lattice ma…
