title: Magnetic response of odd-frequency s-wave Cooper pairs in a superfluid proximity system.
abstract: We investigate the magnetic response of a dirty-normal-Fermi-liquid-spin-triplet-superfluid proximity system consisting of liquid 3He and aerogel. In contrast to bulk superfluids, Pauli spin susceptibility in the proximity system exceeds its normal-state value locally around the interface. This enhanced Pauli paramagnetism originates from odd-frequency s-wave pairing arising due to spatial inhomogeneity. A characteristic observable signature of the paramagnetic effect can be found in the spin susceptibility temperature dependence.
