Abstract

Angular correlation of annihilation radiation (ACAR) from single crystals of [Fe(ptz)₆](BF₄)₂ and [Zn(ptz)₆](BF₄)₂ were measured in the temperature range between 23K and 295K. Large temperature dependence of ACAR spectra for [Fe(ptz)₆](BF₄)₂ around the spin-crossover temperature (130K) was observed. On the contrary, ACAR spectra for [Zn(ptz)₆](BF₄)₂ was almost independent of temperature. The results show that the positronium atom is highly sensitive probe of the spin-crossover transition.
