Lattice, Magnetic, and Electronic Transport Properties in Antiperovskite M3AX Compounds
Description
The compounds M3AX (M: magnetic elements, Mn, Ni, Fe, etc.; A: transition and main group elements, Ga, Cu, Sn, Zn; X: N, C, B) with the so-called “antiperovskite structure” have exhibited a wide range of interesting physical properties, such as superconductivity (SC), giant magnetoresistance (GMR), negative/zero thermal expansion (NTE or ZTE) and nearly zero temperature coefficient of resistivity (NZ-TCR), magnetostriction and piezomagnetic effects, and magnetocaloric effect (MCE), due to strong correlation among lattice, spin, and charge. Therefore, these compounds have attracted great attention. Early reports suggested that the physical properties of these materials are mainly originated from the complex magnetostructure and the induced variable band structure. The strong coupling between crystal structure, magnetic, and even electric ordering parameters and/or fields is also of great interest for the design of novel magnetoelectronic devices. The ability to control and tune the electronic transport, magnetic transition, and abnormal thermal expansion behaviors of these materials makes it worthy to be studied for fundamental research as well as for potential applications.
We invite investigators to contribute original as well as review articles on research and development of physical properties in antiperovskite M3AX compounds, including theoretical calculation and simulation. Relevant high-quality articles on negative/zero thermal expansion phenomena in Invar, ABO3 perovskite compounds, and Fe-based superconductors, whose mechanism is related with magnetovolume effect (MVE) and magnetoelastic coupling, are also accepted. Potential topics include, but are not limited to:
- Magnetic phase transitions, magnetostructure, abnormal thermal expansion phenomena and their mechanism, applications, theoretical calculation, and simulation
- Strong correlation among lattice, spin, and charge, the physical properties and potential applications in the compounds
- Effects under extreme conditions: high pressure, high magnetic field
- MVE in Invar, ABO3 perovskite compounds, and Fe-based superconductors
- Preparation of thin films, composites, and single crystals
