The Heusler-type alloy MgZn2Ce
Single crystals of the MgZn2Ce alloy (magnesium dizinc cerium) were synthesized by a two-step method which couples the thermal treatment of pressed pellets of the pure elements with subsequent arc melting. The compound crystallizes in a Heusler-type (MnCu2Al) structure in the space group Fm\overline{3}m, with one Zn site (site symmetry \overline{4}3m),

A Review on the Magnetovolume Effect of the Full Heusler Alloys Ni2MnZ (Z = In, Sn, Sb)
The full Heusler alloys Ni2MnZ (Z = In, Sn, Sb) exhibit ferromagnetic properties with a Curie temperature (TC) above room temperature. The magnetic properties of Ni2MnZ (Z = In, Sn, Sb) were studied through a combination of experiments and band ...

An experimental study has been performed on a series of Ni2Mn0.4-xFexCr0.6Ga Heusler alloys. At room temperature, the alloys crystallize in either the tetragonal martensite (x < 0.1) or cubic L21 structure (x ≥ 0.1).

Cr0.9Si0.1 protective coatings are developed to enhance the thermal‐shock and oxidation resistance of Mg2Si0.89(Sn0.1,Sb0.01) thermoelectric (TE) materials. The coating forms a dense and adherent barrier that suppresses oxygen diffusion and mitigates mechanical degradation during cyclic oxidation, demonstrating its potential to improve the long‐term ...

Shell-ferromagnetism in Ni-Mn-based Heuslers in view of ductile Ni-Mn-Al
The present work deals with magnetic and structural phase instabilities in Ni-Mn-based Heusler alloys especially Ni-Mn-Al. The temper-annealed Ni50Mn45Al5 Heusler alloy decomposes into the full stoichiometric Ni2MnAl and NiMn phases.

Control of Covalent Bond Enables Efficient Magnetic Cooling
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 ...

Common misconceptions in crystallography and crystal optics
Six recurrent misconceptions in crystallography, some involving mineral and crystal optics, are analyzed and discussed. The explanation of these and similar misconceptions could serve as educational resources for teachers.Did you know that an X‐ray diffraction pattern is not a spectrum?
