Phenomenological thermodynamic theory describing the properties of metastable states in disordered ferromagnets and ferroelectrics with frustrative random interactions is developed and its ability to describe various nonergodic phenomena in real crystals is demonstrated. 
Phenomenological theory of nonergodic phenomena in dipole- and spin-glasses
The path-dependent magnetizations (polarizations) and susceptibilities in dipole- and spin-glasses are described analytically for the standard protocols of temperature and field variations using the
Phenomenological theory of uniaxial relaxor ferroelectrics.
It is found that the phase transition temperature is much higher than the maximum of the dielectric permittivity and very likely corresponds to so-called Burn's temperature and true order parameter has no simple relation with polar modes.
Hysteresis loop signatures of phase transitions in a mean-field model of disordered Ising magnet
The multiplicity of long-lived states in frustrated disordered magnets makes the task to experimentally deter-mine which of them has the lowest free energy (and thus what thermodynamic phase the
Dipole-Glass Concept and History-Dependent Phenomena in Relaxors
The possibility to explain basic physical properties of relaxors within the concept of the dipole-glass transition is discussed. We argue that this concept provides the only consistent picture


Competition between glassiness and order in a multispin glass.
A mean-field multispin interaction spin glass model is analyzed in the presence of a ferromagnetic coupling and the results are consistent with a nonequilibrium thermodynamics that has been proposed for glasses.
The intermediate glassy phase in a ferroelectric with dislocations
This paper examines, in the mean-field approximation, the phase transitions in an elasto-isotropic cubic ferroelectric crystal with randomly distributed ring dislocations. It is found that a
A phenomenological theory of metastable states in disordered Ising magnets
A mechanism of the formation of an exponentially large number of metastable states in magnetic phases of disordered Ising magnets as a result of condensation of fractal delocalized modes near the
Nonanalytic Behavior Above the Critical Point in a Random Ising Ferromagnet
It is shown that in a class of randomly diluted Ising ferromagnets the magnetization fails to be an analytic function of the field $H$ at $H=0$ for a range of temperatures above that at which
Dilute ferroelectric in random electric field: Phase transitions in Pb(Mg1/3Nb2/3)1-x Ti x O3 crystals
Abstract Phase transitions have been studied in single crystals of the ferroelectric solid solutions Pb(Mg1/3Nb2/3)1-x Ti x O3 (PMN–PT) at 0 < x ≤ 0.2. An analysis of the low-frequency (10−1–10−2 H...
We study hysteretic phenomena in random ferromagnets. We argue that the angle dependent magnetostatic (dipolar) terms introduce frustration and long range interactions in these systems. This makes it
Glassy polarization behavior of relaxor ferroelectrics.
The polarization behavior of La-modified lead zirconate titanate relaxors has been investigated for various electrical and thermal histories and the magnitude of both polarizations were found to be equal above a critical temperature.

Random quenched dilution of the triangular-lattice antiferromagnetic Ising model locally relieves frustration, leading to ordering phenomena, which is studied using hard-spin mean-field theory.
Theory of spin glasses
A new theory of the class of dilute magnetic alloys, called the spin glasses, is proposed which offers a simple explanation of the cusp found experimentally in the susceptibility. The argument is
