Neutron diffraction is used to reveal the origin and control of thermal expansion properties cubic intermetallic compounds Mn${}_{3}$Zn${}_{x}$N Mn${}_{3}$[Zn-(Ag,Ge)]${}_{x}$N. We show that introduction Zn vacancies induces stabilizes an antiferromagnetic phase with huge spin-lattice coupling can be tuned achieve zero (ZTE) over a wide temperature range. further ordering (${T}_{N}$) controls this ZTE by chemical substitution, again on site, adjust span temperatures from well above room...
The near zero temperature coefficient of resistivity (NZ-TCR) in Mn-based antiperovskite Mn3Ni1−xCuxN is reported. range NZ-TCR controllable by changing Cu content. Further, the TCR value 0.09 ppm K−1 was obtained Mn3Ni0.5Cu0.5N over a broad around room temperature. anomalous change from metal-like to behavioris apparently due magnetic transition. possible reason for formation interpreted on basis spin-disorder scattering.
Ti, TiN and Au-TiN (Au content: from 0.5% to 7.7%) thin films were deposited on stainless steel substrates by dc reactive magnetron sputtering with a metal Ti target. The crystal structure, surface morphology visible-light reflectivity of the for different film compositions are studied in detail. Distinctly morphologies appear films. It can be observed that is affected Au-doping, when Au content increases 0% 7.7%, roughness enlarges 62.4 82.8 nm. Moreover, varies significantly increasing...
In recent years, it was found that antiperovskite compounds Mn3AX(A=Cu, Zn, Sn, Ni, Al, Ga etc.;X=N/C) exhibit abundant physical properties. Their useful functionalities arising from the interplay between crystal lattice and magnetism, such as superconductivity, giant magnetoresistance, near-zero temperature coefficient of resistance, negative thermal expansion, magnetostriction, piezomagnetic effect, magnetocaloric etc, have aroused great interest. The thorough study structure properties...
The antiperovskite Mn3CuNx thin films are successfully deposited on single crystal Si (100) substrates using facing target magnetron sputtering. effects of nitrogen content the structures and physical properties investigated. structure, composition, surface morphology temperature dependence resistivity magnetization characterized by X-ray diffraction, Auger electron spectroscopy, atomic force microscope, photoelectron property measurement systems superconducting quantum interference device....
