TL;DR
This study uses muon-spin rotation to reveal that CePt2In7 exhibits commensurate antiferromagnetic order below 5.40 K, with the magnetic order parameter fitting a strong-coupling gap-energy model.
Contribution
First muSR investigation of CePt2In7 demonstrating its magnetic ordering and detailed temperature dependence of the order parameter.
Findings
Antiferromagnetic order below 5.40 K
Order parameter fits a strong-coupling gap model
Provides microscopic magnetic insights into CePt2In7
Abstract
The low-temperature microscopic magnetic properties of the quasi-2D heavyfermion compound, CePt2In7 are investigated by using a positive muon-spin rotation and relaxation (?muSR) technique. Clear evidence for the formation of a commensurate antiferromagnetic order below TN=5.40 K is presented. The magnetic order parameter is shown to fit well to a modified BSC gap-energy function in a strong-coupling scenario.
