TL;DR
This study uses TDPAC to measure hyperfine fields in ZrZn2, revealing complex magnetic ordering with larger local moments than macroscopic data suggest, indicating it is not a simple ferromagnet.
Contribution
First application of TDPAC to ZrZn2 revealing detailed magnetic hyperfine interactions and complex magnetic structure.
Findings
Zr has a larger local magnetic moment than macroscopic measurements indicate.
Induced magnetic moments are present at Zn sites.
ZrZn2 exhibits complex magnetic ordering beyond simple ferromagnetism.
Abstract
Time differential perturbed angular gamma-gamma-correlation (TDPAC) method on 111Cd nuclei probes inserted in ZrZn1.9 is used to measure the magnetic hyperfine fields (MHF) at Zr and Zn sites and the electric field gradient (EFG) Vzz at Zn sites as a function of temperature at various pressures and as a function of pressure at the temperature 4 K. Our data indicate that the local magnetic moment of Zr in the magnetically ordered state is substantially larger than its value obtained from the macroscopic measurements and that there is also an induced magnetic moment at the Zn site. We conclude that ZrZn2 is not a simple ferromagnet and discuss a possible type of its magnetic ordering.
