Abstract

We report on the electron spin resonance (ESR) of Eu²⁺ in EuT₂P₂ (T=Mn, Zn, Cd) single crystals. The temperature dependencies of ESR linewidth and resonance shift show a similar behaviour when approaching the Eu-ordered state -- a divergence towards T_{\rm N}, indicating the growing importance of magnetic correlations and the build-up of internal magnetic fields. For T=Mn an additional temperature scale of ≈ 47~K has considerable impact on linewidth, resonance field and intensity. This points to the presence of Mn magnetic correlations which yet were not reported.
