Description
We found Majorana-Weyl fermions in a chiral superconductor Sr2RuO4. The current-voltage curves reveal anomalous behavior: The induced voltage is an even function of the bias current. The zero-bias conductance peak was observed through the tunnel junction at the edge. The magnetic-field dependence suggests the excitation of the Majorana-Weyl fermions along the closed chiral edge current of the single domain under a bias current. We also discuss the relationship between a change in the chirality and the spontaneous magnetization of the single domain Sr2RuO4.
