Substitutions options for Mn2+ doped YAl3(BO3)(4) crystal at room temperature have been analyzed in detail using a semiempirical superposition model (SPM) analysis, which enables correlation of the spectroscopic and crystallographic data. The very large zero-field splitting parameter (ZFSP) b(2)(0)(= D) for Mn2+ ion in YAl3(BO3)(4) crystal observed by electron magnetic resonance (EMR) has been interpreted in the framework of SPM. It is considered that the replacement of the Mn2+ for Al3+ induces a sizable lattice distortion, which gives rise to a large D value. It is also indicated that the zero-field splitting depends linearly on the angular distortion of the ligands around Mn2+ doped into YAl3(BO3)(4).
