The quadratic electric field effect for cubic Gd 3+ centers in MF 2 single crystals is discussed in terms of the quasimolecular and superposition model. Very high electric fields (above 300 kV/cm) are required to observe this effect. Zero‐field splitting of Gd 3+ ions in the crystal field is also discussed. It is shown that these models interpret the changes in the induced B 2 0spin‐Hamiltonian parameter consistently.
