Abstract
Thermal expansion and magnetostriction measurements on single crystalline , a very clean, strongly Pauli-limited, heavy-fermion superconductor (≃1.82 K), have been utilized to establish a first-order transition at T≤T̃≃1.5 K and B<(T). This is ascribed to the hitherto unobserved formation of a nonuniform superconducting state, as pedicted theoretically in 1963.
