摘要：

Thermal expansion of magnetostriction measurements on single crystalline UPd2Al3, a very clean, strongly Pauli-limited, heavy-fermion superconductor (T(c) congruent-to 1.82 K), have been utilized to establish a first-order transition at T less-than-or-equal-to T congruent-to 1.5 K and B < B(c2)(T). This is ascribed to the hitherto unobserved formation of a nonuniform superconducting state, as predicted theoretically in 1963.
