Adjustable Zero Thermal Expansion in Antiperovskite Manganese Nitride

Thermal expansion and electrical properties of stannum doped manganese nitrides and composites

“…have been developed by partially substituted or co-doped by different elements in Mn 3 CuN [1,9,10]. The broad negative thermal expansion operation temperature window and a near zero thermal expansion could also be realized from the nanosized Mn 3 Cu 1−x Ge x N fabricated by spark plasma sintering (SPS) [11][12][13]. Besides thermal expansion properties, the mechanical properties, temperature coefficient of resistivity and thermal conductivity of these manganese nitrides were also explored as the metallic ceramic [14][15][16].…”

Effects of carbon deficiency on the magnetic interactions in GaCMn3, a critical behavior study

“…In the past years, the Mn-based antiperovskites AXMn 3 (A: metal or semiconducting elements, X: C or N) has attracted increasing interest because of the observation of various functionalities, such as giant magnetoresistance (GMR) [1][2][3], large magnetocaloric effect (MCE) [4][5][6][7], negative or zero thermal expansion (NTE or ZTE) [8][9][10][11][12], nearly zero temperature coefficient of resistance (TCR) [13][14][15][16], and giant magnetostriction (MS) [17,18]. AXMn 3 usually has a simple cubic crystal structure (space group, Pm m 3 − ), in which element A locates at the corner positions, X at the body center, and Mn at the face centers [19].…”

Low-temperature abnormal thermal expansion property of Mn doped cubic NaZn13-type La(Fe, Al)13 compounds

“…The thermal induced strain usually gives rise to materials' physics and function failure originated from the undesirable mismatch of the coefficient of thermal expansion (CTE) in different components [1] and the decline in the precision of thermometric instruments [2] . Therefore the abnormal thermal expansion (ATE) property including zero thermal expansion (ZTE) and negative thermal expansion (NTE) has become an advanced research focus especially in high-precision devices.…”

“…Therefore the abnormal thermal expansion (ATE) property including zero thermal expansion (ZTE) and negative thermal expansion (NTE) has become an advanced research focus especially in high-precision devices. In recent years, several kinds of materials with ATE property have been discovered, such as LiAlSiO4 (β-eucryptite), ZrW2O8, [3] ScF3, [4,5] PbTio3-based compounds, [6] La(Fe, Si)13-based compounds [7][8][9][10] and some antiperovskite manganese nitrides [2,11] . It is noteworthy that most of ATE materials are tuned to adjust the temperature range of ATE moving towards higher temperature span.…”
