Control of Covalent Bond Enables Efficient Magnetic Cooling

Advanced Materials, Volume 38, Issue 7, 2 February 2026.
Giant and reversible magnetocaloric effect (MCE) is achieved by tuning covalency through sub‐unit‐cell chemical engineering, establishing a novel design principle for effective hysteresis control in magnetocaloric materials. Abstract Magnetic cooling, harnessing the temperature change in matter when exposed to a magnetic field, presents an energy ...

Fundamentals of half-metallic Full-Heusler alloys

, 2008
Intermetallic Heusler alloys are amongst the most attractive half-metallic systems due to the high Curie temperatures and the structural similarity to the binary semiconductors.

Exchange interactions and temperature dependence of the magnetization in half--metallic Heusler alloys

, 2005
We study the exchange interactions in half-metallic Heusler alloys using first-principles calculations in conjunction with the frozen-magnon approximation. The Curie temperature is estimated within both mean-field (MF) and random-phase-approximation (RPA)

Slater-Pauling Rule and Curie-Temperature of Co$_2$-based Heusler compounds

, 2005
A concept is presented serving to guide in the search for new materials with high spin polarization. It is shown that the magnetic moment of half-metallic ferromagnets can be calculated from the generalized Slater-Pauling rule.
