It is shown that antiferromagnetic ordering in doped manganites with strong double-exchange interaction is transformed into ferromagnetic canted ordering with residual antiferromagnetic behavior in the basal plane as a result of hopping of mobile ele

The theory describing electron spin resonance (ESR) and the longitudinal magnetization response of coupled spin systems in a metal containing both delocalized conduction electrons (“espins”) and localized paramagnetic centers (“s-spins”) is g

The spin system of many new promising materials, such as high-temperature superconductors, fullerenes, fullerides, or manganites with colossal magnetoresistance, consists of localized spins (s-spins of impurity paramagnetic centers) and delocalized s

The transverse response (transverse dynamic susceptibility) of coupled localized (s) and delocalized (e) electron spins of a metal paramagnet as well as the longitudinal dynamic response of such a system (to be registered by a longitudinal coil) to t

An investigation based on the coupled Maxwell-Bloch equations for a system of equivalent exchange-coupled spins is performed in order to explain a number of features of NMR spectra obtained in metals by Fourier-transforming of the free-induction deca

We propose a model of radiofrequency (rf) superradiance by a system of interacting nonequivalent spins in a point specimen. In contrast to the rf superradiance observed and described earlier, here spin-spin coupling acts as the interaction with the c

The paper presents a semiclassical treatment of the nuclear magnetization vector m evolution of an initially negatively polarized nuclear spin system into a superradiant (SR) state in the case when m interacts with an LC-circuit, possessing a ringing
