Zero field muon spin rotation and relaxation (mu SR) measurements on a single crystal of orthorhombic PrCoAl4 revealed the presence of spontaneous static fields, extending above the well-known incommensurately modulated antiferromagnetic structure (T-N=17 K) up to at least 110 K. Two further transitions at 30 K and 84 K were clearly visible. The spontaneous fields above T-N are confined to the (b,c) plane and are tentatively ascribed to a spin density wave involving the Co 3d-band electrons.
