Transition-metal compounds have been a focus of intensive studies due to their rich physical properties and potential applications in functional devices such as the colossal magnetoresistance in manganites, the spin-state transition in cobaltites, the high-temperature superconductivity in cuprates or iron pnictides, and the charge-density wave and superconductivity in intercalated or substituted dichalcogenides. Researchers try to study the variation of crystal structure and transport properties caused by changing physical parameters such as different chemical substitution, applied pressure, magnetic field, electric field, or photo irradiation to investigate the underlying physics in terms of the unusually strong coupling among the charge, spin, orbit, and lattice degrees of freedom. Since the magnetic properties and electrical and thermal transport of transition-metal compounds are determined by the d electrons with the fivefold orbital degeneracy, understanding of the d-orbital state is one of the key issues required to develop fundamental physics of transition-metal compounds as well as its application.

This important issue is devoted to the investigation of crystal structure, magnetic properties, electrical transport, and thermal transport in the correlated electron systems based on transition-metal compounds. We welcome experimental and theoretical researchers to contribute original and outstanding research articles as well as review articles, which provide a comprehensive report on the present progress of the field in condensed matter physics. Potential topics include, but are not limited to:

• Sample fabrication of transition-metal compounds such as polycrystalline, single crystals, and thin films
• Characterization of crystal structure such as lattice parameters, bond length, and bond angles
• Magnetic properties based on magnetic susceptibility and hysteresis loop
• Magnetic resonance such as electron spin resonance and nuclear magnetic resonance
• Electrical transport based on resistivity and magnetoresistance effect
• Thermal transport based on heat capacity, thermoelectric power, and thermal conductivity
• Ferromagnetism, antiferromagnetism, metal-insulator transition, spin-state transition, charge ordering, orbital ordering, spin polarization, phase separation, charge-/spin-density wave, and superconductivity
