“…Knowledge of the gap function enables us to calculate the total normalized density of states, defined as [50]: Also from the solution of the Eliashberg equations formulated on the real frequency axis we determined the value of the electron effective mass at T C . In particular, for CdCNi 3 we obtained m e = 1.81m e , wherein the MgCNi 3 is characterized by m e = 2.55m e [13]. At this point it should be emphasized that the value of m e is directly related to the electron-phonon coupling constant and in a simple analytical way this fact can be written as m e (1 + λ)m e .…”

“…During the comparison of the thermodynamic properties of sister antiperovskites CdCNi 3 and MgCNi 3 we can conclude that the larger mass of Cd-ion than Mg-ion is the cause of the deterioration of the superconducting properties of CdCNi 3 .…”

“…B. Kemmerer and studied by Rose [1]. In the ideal form the perovskite-type materials adopt a structure with the general stoichiometry ABX 3 , where A and B are cations at the center and at the corners of the unit cell, respectively, and X are anions (usually oxygens) situated at the face center of the edges of the unit cell [2]. Perovskites exhibit many interesting and intriguing properties from both the theoretical and the experimental point of view.…”

“…Perovskites exhibit many interesting and intriguing properties from both the theoretical and the experimental point of view. Potential applications of these materials are associated with the unique features such as a near-zero temperature coefficient of resistivity [3], negative thermal expansion [4], high-temperature superconductivity [5], magnetostriction [6], and giant magnetoresistance [7]. The above properties result from a complex interplay between the crystal structure, electronic state of the transition metal and amount of defects [8].…”

“…Literature reveals that in CdCNi 3 , AlCNi 3 and ZnNNi 3 also exhibit superconductivity [28][29][30][31][32]. In particular, Uehara et al observed in the experimental work that CdCNi 3 is a superconductor with T C = 2.5-3.2 K and also does not show ferromagnetism [33].…”

We investigate the thermodynamic parameters of the superconducting antiperovskite CdCNi 3 using the Eliashberg approach which is an excellent tool to the exact characterization of the conventional superconductors. In particular, we reproduce the measured superconducting transition temperature (T C = 3.2 K) for a high value of the Coulomb pseudopotential (μ C = 0.22). Then we determine the energy gap, the thermodynamic critical field and the specific heat for the superconducting and normal state. On this basis, we show that the thermodynamic properties of CdCNi 3 differ slightly from the prediction of the Bardeen-Cooper-Schrieffer theory, which means that CdCNi 3 is a medium-coupling superconductor in contrast to related strongcoupling MgCNi 3 .

Multicomponent magnetic phase diagrams are a key property of functional materials for a variety of uses, such as manipulation of magnetization for energy efficient memory, data storage, and cooling applications. Strong spin-lattice coupling extends this functionality further by allowing electricfield-control of magnetization via strain coupling with a piezoelectric. Here this work explores the magnetic phase diagram of piezomagnetic Mn 3 NiN thin films, with a frustrated noncollinear antiferromagnetic (AFM) structure, as a function of the growth induced biaxial strain. Under compressive strain, the films support a canted AFM state with large coercivity of the transverse anomalous Hall resistivity, ρ xy , at low temperature, that transforms at a welldefined Néel transition temperature (T N ) into a soft ferrimagnetic-like (FIM) state at high temperatures. In stark contrast, under tensile strain, the low temperature canted AFM phase transitions to a state where ρ xy is an order of magnitude smaller and therefore consistent with a low magnetization phase. Neutron scattering confirms that the high temperature FIM-like phase of compressively strained films is magnetically ordered and the transition at T N is first-order. The results open the field toward future exploration of electricfield-driven piezospintronic and thin film caloric cooling applications in both Mn 3 NiN itself and the broader Mn 3 AN family.

A baromagnetic effect in a novel tetragonal magnetic structure is introduced by vacancies in Mn3 Ga0.95 N0.94 , due to the change of the Mn-Mn distance and their spin re-orientation induced by a pressure field. This effect is proven for the first time in antiperovskite compounds by neutron powder diffraction analysis. This feature will enable wide applications in magnetoelectric devices and intelligent instruments.
