Pressure-induced phase transition in lanthanum ethylsulfate with praseodymium impurity
Voloshin V. A., Ivchenko L. A.
Measurements of the absorption spectra of LaES (lanthanum ethylsufate) (1% Pr3-1") and PrES (praseodymium ethylsulfate) have revealed a phase transition at pressures above 26 kbar and temperatures below 150 K.
