The application of high pressures to solids has been, and continues to be, a powerful tool to probe the exotic states of matter found in many solid-state systems. High pressures provide an avenue to cleanly tune fundamental parameters associated with superconductivity, magnetism, and quantum criticality in an attempt to garner information about these novel and poorly understood phenomena. The effects of chemical substitution and/or pressure upon the superconducting and antiferromagnetic ordered states of the CeRh₁-xCoxIn5 system, the ferromagnetism in the compound Au₄V, the superconducting and "hidden order" phases of the heavy fermion compound URu₂Si₂ and the related, substituted URu₂-xRexSi₂ system, and the superconducting phase of Th have been investigated up to pressures as high as 400 kbar using various techniques
