Abstract

The temperature dependence of the magnetic susceptibility is analyzed at some constant pressures by a power-law formula using the experimental data from the literature for the alpha - beta and beta - gamma transitions in oxygen. A weak discontinuous (nearly continuous) transition occurring from the a to the beta phase, becomes more discontinuous (weakly first order) for the beta - gamma transition as observed experimentally, which can be explained in terms of the critical exponents deduced from our analysis.
