On the zero-point spin-fluctuations in itinerant-electron metamagnetism
YAMADA, Hideji
The effect on the magnetic equation-of-state of the zero-point spin fluctuations, together with the thermal ones, in an itinerant-electron system is discussed on the Landau-Ginzburg theory. It is shown that the zero-point spin fluctuations do not affect the results obtained previously by the spin fluctuation model for the itinerant-electron metamagnetism, when the Landau coefficients renormalized by the zero-point spin fluctuations are made use of. It is also shown that the contributions from the zero-point spin fluctuations at high temperatures are included in the results obtained on the static Gaussian statistics.
