Magnetostriction in Mn3CuN

Abstract: Discovery of large magnetostriction in an antiperovskite Mn3CuN is reported. Mn3CuN undergoes the first-order transition from high-temperature (high-T) paramagnetic to low-temperature ferromagnetic (FM) phase at the Curie temperature TC=143K, accompanied by cubic-to-tetragonal structural deformation. In the tetragonally distorted FM phase, Mn3CuN, even in a polycrystalline form, expands 0.2% and shrinks 0.1% in the direction parallel and perpendicular to the external field of 90kOe, respectively. This magnetos… Show more

“…The volume change reaches 2%, which is among the largest for magnetic metals, next to 4% volume change in YMn 2 [44]. Manganese antiperovskites exhibit many other advantageous features such as magnetostriction [61][62][63], magnetocaloric effects [64,65], magnetoresistance effects [66,67], and a low temperature coefficient of resistance [68][69][70], and hence attract great attention as a reservoir of functionalities.…”

“…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].…”

“…6 On the other hand, layered superconductors often proclaim new physics, such as p-wave spin-triplet superconductor Sr 2 RuO 4 . 7 In recent years, the antiperovskite carbides AXM 3 (X, carbon, boron or nitrogen; M, transition metal) have attracted considerable attention due to lots of interesting properties, such as superconductivity, 8,9 non-Fermi liquid behavior, 10 strong electron-electron correlation, 11 giant magnetoresistance (MR), 12,13 large negative magnetocaloric effect (MCE), 14,15 giant negative thermal expansion, 16,17 magnetostriction, 18 and nearly zero temperature coefficient of resistivity. 19 Specially, in MgCNi 3 despite the strong expectation for ferromagnetism due to full occupancy of Ni, it shows superconductivity with a T C about 8 K. 8 Experiments and energy band calculations show that there is a van Hove singularity in the density of states (DOS) just below Fermi level (E F ), which leads to a large DOS at the E F (N(E F )), dominated by Ni-3d states.…”
