Abstract:
We find the spin oscillation branch with the frequency $\omega=(\mu H/\hbar)(k/k_{\operatorname{c}})^2$ in the paramagnetic phase for systems with exchange interaction in the presence of an external magnetic field $\vec H$.
Keywords:
spin fluctuations, spin dynamics, exchange interaction, current, dynamical magnetic susceptibility tensor.
