摘要：

Measurements of the EPR spectrum of seven scheelite structure crystals doped with Mn2+ ions are performed in the temperature range from 4.2 to 350 K. Experimental data of a preceding paper [1] are completed. The temperature dependent zero field splitting is discussed in terms of implicit and explicit contributions. Being the most important one the temperature effect of b 20 is described with an Einstein model where the impurity force constant is related to regular cationic vibrations by a Born‐Mayer potential.
