Abstract

The temperature dependence of the single-crystal elastic constant

C_{44}

of rutile-structure Mg

F_{2}

and Ti

O_{2}

(rutile) has been measured between room temperature and 4.2 K.

C_{44}

of Mg

F_{2}

is seen to exhibit anomalous softening below 50 K, similar to the softening observed in Mn

F_{2}

, Ni

F_{2}

, and Zn

F_{2}

, while

C_{44}

of Ti

O_{2}

shows normal behavior.
