Abstract
The magnetic order of Pr in nonsuperconducting PrBa2Cu3O7 has been studied by specific-heat, susceptibility, and neutron-diffraction measurements. The basic ordering consists of a simple antiferromagnetic arrangement, with a saturated moment of 0.241/4B and a Néel temperature TN of 1/417 K, which is two orders of magnitude higher than expected from either dipolar or Rudeman-Kittel-Kasuya-Yosida interactions alone. The small moment, along with the large value of the low-temperature electronic specific-heat coefficient of 196 mJ/mol K2, suggests that there is substantial f-electron character at the Fermi level.
