The effects of thermal fluctuations on the ground state phases of two dimensional frustrated mixed- spin systems with anisotropic exchange interactions are investigated and the sign change of the magnetocaloric parameter inside the solids and the Mott insulator is shown, which is a characteristic of ordered phases.

Understanding A and B-site engineered lead-free Ba(1−x)CaxZryTi(1−y)O3 piezoceramics: a perspective from DFT
DFT has been used to investigate the structural and polarization of Ba(1-x)CaxZryTi(1−y)O3, perovskite solid solutions namely BaTiO3 (BT), Ba(Zr0.125Ti0.875)O3 (BZT), (Ba0.875Ca0.125)TiO3 (BCT) and
Strain and vector magnetic field tuning of the anomalous phase in Sr3Ru2O7
The components of the field-induced order in Sr3Ru2O7 coexist microscopically, not, as has long been thought, in domains, but both are consistent with a multicomponent order parameter that is likely to preserve the point-group symmetry of the lattice, but is highly susceptible to perturbation.
Quantum Criticality and Metamagnetism of Strained \(\mathrm{Sr}_3\mathrm{Ru}_2\mathrm{O}_7\)
As outlined in Chap. 1, the field of strongly correlated electrons is dominated by emergent phenomena exhibiting exotic and intriguing properties. Identifying and characterising these phases has been
Theory of the strange metal Sr3Ru2O7
It is shown how the behavior of strontium ruthenate, a widely studied strange metal, follows in detail from well-established electronic properties, and a scattering process in which two electrons from the large, “cold” Fermi surfaces scatter into one hot and one cold electron renders the ostensibly noncritical cold fermions a marginal FermI liquid.
Multicritical Fermi Surface Topological Transitions.
It is shown that higher order singularities, where multiple disconnected leaves of Fermi surface touch all at once, naturally occur at points of high symmetry in the Brillouin zone, which can lead to stronger divergences in the density of states than canonical van Hove singularities.

Entropy Landscape of Phase Formation Associated with Quantum Criticality in Sr3Ru2O7
It is shown that combining measurements of the magnetocaloric effect and specific heat allows a comprehensive study of the entropy of a system, and this technique should offer a way to probe other materials to reveal unusual properties, such as novel metallic states and superconductivity.
