Weakly Anisotropic Superconductivity of Pr₄Ni₃O₁₀ Single Crystals.

ABSTRACT: Since the discovery of high-temperature superconductivity, studying the upper critical field and its anisotropy has been crucial for understanding the superconducting mechanism and guiding applications. Here, we perform in situ high-pressure angular-dependent electrical transport measurements on Pr₄Ni₃O₁₀ single crystals using a custom diamond anvil cell (DAC) rotator, confirming its anisotropic superconductivity. The anisotropy parameter γ, derived from the upper critical fields (μ₀H_c2) for H⊥ab and H//ab, is approximately 1.6, decreasing with increasing temperature and approaching 1 near T_c.
