Origin of the Unusual Temperature Dependence of the Upper Critical Field of Kagome Superconductor CsV3Sb5: Multiple Bands or van Hove Singularities?
Ramakanta Chapai, Alexei E. Koshelev, Matthew P. Smylie +8
Van Hove singularities (vHs) located close to the Fermi level in Kagome superconductors AV3Sb5 (A = K, Rb, Cs) have profound influence on their electronic and transport characteris…

Anisotropic Paramagnetic Peak Effect in Reversible Magnetization of Crystalline Miassite Superconductor
Ruslan Prozorov, Makariy A. Tanatar, Marcin Kończykowski +5
We report an unusual anisotropic paramagnetic peak effect observed in reversible magnetization of a single crystalline nodal superconductor . Both temp…

On temperature-dependent anisotropies of upper critical field and London penetration depth
V. G. Kogan, R. Prozorov, A. E. Koshelev
We show on a few examples of one-band materials with spheroidal Fermi surfaces and anisotropic order parameters that anisotropies of the upper critical field and of the…
