Abstract
It is known that PrCu2 shows a modulated antiferromagnetic structure b elow T-N=(50-60) mK that is claimed to be of a cooperative nuclear-ele ctronic nature [S. Kawarazaki and J. Arthur, J. Phys. Sec. Jpn. 51, 10 77 (1988)]. Here we report on an observation by muon spin-rotation spe ctroscopy that this order seems to persist on a short-range scale with an apparently unchanged structure up to 60 K, i.e., up by three order s of magnitude as compared with T-N. We conjecture that the apparent m agnetic order is of a secondary nature and the primary mechanism invol ves quadrupolar effects.
