High pressure Raman spectroscopy of spinel-type ferrite ZnFe2O4

An in-situ Raman spectroscopic study was conducted to explore the pressure induced phase transformation of spinel-type ferrite ZnFe2O4. Results indicate that ferrite ZnFe2O4 initially transforms to an orthorhombic structure phase (CaFe2O4polymorph) at a pressure of 24.6 GPa. Such a phase transformation is complete at 34.2 GPa, and continuously remains stable to the peak pressure of 61.9 GPa. Th...

Ultrasound velocity measurements in liquid media

This review is a survey of the authors` scientific investigations in the field of ultrasound velocity measurements in electrolyte solutions and various liquid systems. Measurements were performed with a specially designed ultrasonic-laser interferometer and a pulse-echo system. The main molecular acoustic interferometric experiments were provided in aqueous solutions of nine lanthanide nitrates...

High field properties of geometrically frustrated magnets

Above the saturation field, geometrically frustrated quantum antiferromagnets have dispersionless low-energy branches of excitations corresponding to localized spin-flip modes. Transition into a partially magnetized state occurs via condensation of an infinite number of degrees of freedom. The ground state below the phase transition is a magnon crystal, which breaks only translational symmetry ...

Geometrically frustrated antiferromagnets: statistical mechanics and dynamics

1.1 Introduction This chapter is intended to give an introduction to the theory of thermal fluctuations and their consequences for static and dynamic correlations in geometrically frustrated antiferromagnets, focusing on the semiclassical limit, and to discuss how our theoretical understanding leads to an explanation of some of the main observed properties of these systems. A central theme will...

Critical slowing down in the geometrically frustrated pyrochlore antiferromagnet Gd2Ti2O7

Longitudinal-field muon spin relaxation experiments have been carried out in the paramagnetic state of singlecrystal Gd2Ti2O7 just above the phase transition at Tm = 1.0 K. At high applied fields the exponential relaxation time T1 is proportional to field, whereas T1 saturates below a crossover field Bc that is ∼2.5 T at 1.5 K and decreases as Tm is approached. At low fields the relaxation rate...
