Pauli-limit upper critical field of high-temperature superconductor La(1.84)Sr(0.16)CuO(4)

The upper critical field of a cuprate high-temperature superconductor, La(1.84)Sr(0.16)CuO(4), was investigated by high-frequency self-resonant contactless electrical conductivity measurements in magnetic fields up to 102 T. An irreversible transition was observed at 85 T (T = 4.2 K), defined as the...

description The upper critical field of a cuprate high-temperature superconductor, La(1.84)Sr(0.16)CuO(4), was investigated by high-frequency self-resonant contactless electrical conductivity measurements in magnetic fields up to 102 T. An irreversible transition was observed at 85 T (T = 4.2 K), defined as the upper critical field. The temperature-dependent upper critical field was argued on the basis of the Werthamer-Helfand-Hohenberg theory. The Pauli-limiting pair-breaking process with a small contribution of the spin-orbit coupling explained the first-order phase transition exhibiting a hysteresis observed at low temperatures.
