Single-phase antiperovskite nitride GeNCo3 with space group Pm3̅m is successfully synthesized by a solid–gas reaction. The crystal structure, magnetism, specific heat at low temperatures, Hall effect, and electrical and thermal transport properties are widely investigated. Exhilaratingly, a canonical spin-glass (SG) behavior is observed in GeNCo3 with a freezing temperature T0 = 79.43 K, dynamical exponent zν = 6.156, and flipping time τ0 = 5.0 × 10–12 s. The origin of the SG state in GeNCo3 is likely due to the atomic disorder introduced by the Ge vacancies. This is further proven by the measurements of Ge0.9NCo3 with more Ge deficiencies.

钴基氮化钙钛矿GeNCo 3中自旋玻璃行为的观察
单相antiperovskite氮化GENCO 3空间群PM 3米成功通过固-气反应来合成。广泛研究了晶体结构，磁性，低温比热，霍尔效应以及电和热传输性质。令人欣喜的规范自旋玻璃（SG）行为在GENCO观察到3有冷冻温度Ť 0 = 79.43 K，动态指数zν = 6.156，和翻转时间τ 0 = 5.0×10 -12秒。GeNCo 3中SG国家的起源这很可能是由于Ge空位引入的原子无序造成的。测量具有更多Ge缺陷的Ge 0.9 NCo 3进一步证明了这一点。
