The paper is devoted to the searching for order parameter of low-temperature phase transitions in divalent nitrates Pb(NO3)2, Sr(NO3)2 and Ba(NO3)2. According to the curves of temperature dependencies of the quadratic susceptibility tensor component c14, the conclusion is made that the low-temperature phase transitions in divalent nitrates are the phase transitions of the first order with the features of the second order. The mechanisms of the low-temperature phase transitions in divalent nitrates are discussed from this perspective. |
