Summary: This study reports materials with negative, zero, and positive thermal expansion behaviors, which are hexagonal CrTe, monoclinic Cr3Te4, and trigonal Cr5Te8 in NiAs-type defective Cr1-delta Te. These materials show obvious anisotropic thermal expansion and the properties are confirmed to be originated from the magnetovolume effect through magnetic measurements. The materials with similar compositions but different structures provide a new research direction for tuning the negative thermal expansion properties of materials and searching for materials with zero thermal expansion.

Summary: In this study, the hysteretic loss and evolution of magnetocaloric behavior in Mn1xCdxCoGe system were investigated. It was found that the replacement of Mn by Cd can regulate the Curie temperature without altering the crystal structure. The critical parameters extracted by different techniques reveal the long-range ordering magnetic interactions. The effect of increasing and decreasing fields on the temperature average entropy changes and normalized refrigerant capacity was also discussed to further explore the performance of magnetic refrigeration.

Summary: The principal factors leading to efficient AC field-induced heating of magnetic fluids are determined based on measurements of magnetic and calorimetric properties of NaFeO2 nanoparticles and their fluids. The magnetic behavior and parameters of NaFeO2 nanoparticles are identified, and the relationship between fluid caloric properties and AC magnetic field amplitude and nanoparticle concentration is analyzed. It is found that the heating efficiency of weakly coercive NaFeO2 nanoparticles shows an amplitude threshold character and the heating rate is critically dependent on AC magnetic field amplitude.
