摘要
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. The magnetic field dependence of the differential susceptibility is also analyzed in this study for the alpha - O-2 at 4.2 K by a power-law formula using the experimental data. lambda-type of observed behaviour of the differential susceptibility is discussed in terms of our analysis for the alpha - O-2.
