Anomalous behavior of the dielectric constant of the system Fe1.6Cr1.4O4
Belov K. P., Goryaga A. N., Sheremet'ev V. N.
At Tc = 337 К the dielectric constant of the system Fe1.6Cr1>404 behaves anomalously. This anomalous behavior of the sample is accompanied by a substantial change in its size. It is assumed that at this temperature the compound undergoes a transition to the polar state.
