									<p>Abstract:</p>
<p>A hallmark for unconventional superconductivity is the non-<em>s</em>-wave pairing symmetry of the superconducting order parameter (OP). The&nbsp;<em>s</em>-wave pairing was assumed in the original BCS theory of superconductivity. Sr<sub>2</sub>RuO<sub>4</sub>&nbsp;and UTe<sub>2</sub>, for which a non-<em>s</em>-wave pairing is quite well established, are two promising candidates for the more exotic odd-party, spin-triplet superconductors. While Sr<sub>2</sub>RuO<sub>4</sub>&nbsp;is the first and only layered perovskite superconductor with the normal electronic states on the Fermi surface formed primarily out of 4d orbitals, UTe<sub>2</sub>&nbsp;is a (recently discovered) heavy fermion superconductor possessing a highly anisotropic Fermi surface with electronic states dominated by strongly correlated 5f electrons of U. Both Sr<sub>2</sub>RuO<sub>4</sub>&nbsp;and UTe<sub>2</sub>&nbsp;are furthermore likely candidates for the spin-fluctuation-mediated pair formation proposed originally for superfluid&nbsp;<sup>3</sup>He. In this talk I will give a brief overview of the experimental work on Sr<sub>2</sub>RuO<sub>4</sub>&nbsp;and UTe<sub>2</sub>&nbsp;that is most relevant to the unconventional nature of superconductivity and discuss our own work on the phase-sensitive determination of the symmetry properties of the OP in these two superconductors.</p>
