Abstract

A cubic symmetry site is reported for Gd$^{3+}$ in Cs$_2$NaInCl$_6$ at room temperature. The temperature dependence of the cubic spin-Hamiltonian parameter has been measured in the temperature interval 6--300 K using electron paramagnetic resonance (EPR) spectrometry. A thorough EPR examination for a crystal sample clearly demonstrates that there are no new symmetry sites arising in the temperature interval under study (6-300 K) suggesting, therefore, that the site symmetry remains cubic. We fit an analytical expression for the cubic spin-Hamiltonian parameter $b_4^0$ as a function of temperature. The absolute sign of this spin Hamiltonian parameter is also determined.
