The low temperature phase diagrams have been determined for the potassium benzoate – water and the sodium benzoate – water systems. The ice eutectics with these anhydrous alkali benzoates were found at −11.8 °C with 34.89% potassium benzoate and at −14.5 °C with 39.7% sodium benzoate. Previously reported hydrates of potassium benzoate (3) were not observed. Concentrated sodium benzoate solutions below 0 °C were found to attain equilibrium with sodium benzoate only with the greatest difficulty.

ABSTRACTRecent experiments on magnetically-ordered ternary and pseudoternary rare earth superconductors are briefly reviewed. Superconductivity has been found to coexist with antiferromagnetic order, but to be destroyed by the onset of ferromagnetic order at a second transition temperature Tc2∼TM, where TM is the Curie temperature. In antiferromagnetic superconductors, the antiferromagnetic order modifies superconducting properties such as the curve of the upper critical magnetic field versus temperature. In ferromagnetic superconductors, a long wavelength (∼ 102 Å sinusoidally modulated magnetic state develops in the superconducting state as a result of the superconducting-ferromagnetic interactions. The interplay of superconductivity and competing magnetic interactions in pseudoternary rare earth systems produces complex and interesting low temperature phase diagrams.
