| Popis: | A substantial magnetic contribution into specific heat capacity is found in monocrystalline ErAl3(BO3)4 at temperatures below 5 K. The results of measured ESR spectra at 4,2 K confirm manifestation of short-range magnetic order as well. The obtained data is discussed invoking the model accounting for spin-spin interaction between rare-earth ions in paired clusters. |
